co2 regulator Buyer’s Guide

If you keep the before points in mind, you can easily go out to the market and buy co2 regulator, right? No!

How They Work

A nitrogen regulator basically reduces the highly pressurized gas or liquid from the tank into a more usable form. Without a nitrogen regulator, you wouldn’t be able to control the flow of the liquid from the pressurized tank and all of it would be released at once as a result of the high pressure.

A nitrogen regulator comes in a variety of styles that are all intended for a specific use in mind. There are primary nitrogen regulators, secondary and also panel models along with a combination nitrogen/Coregulator.

For applications that include dispensing beer or wine, a primary regulator is used to reduce the pressurized contents.

Secondary gas regulators are designed to further reduce the pressure from the primary regulator or gas blender to control the flow from the individual beer keg.

The panel regulator is intended for use in the walk-in or large display coolers. A primary COor nitrogen regulator dispenses at between 35-4PSI and supplies two adjusted secondary regulators that reduce that pressure to 1and 1PSI.

How They Compare

The Uniweld RHP400: This model has some drawbacks as it only goes up to a 400 PSI Delivery Pressure at maximum. But that issue aside, this is a fairly decent product at an affordable price.

The Pro CO2: This regulator has the standard ¼ inch male connector and boasts a maximum of 800 PSI and is made of durable brass. All and all, this is a decent and practical choice for a nitrogen regulator.

The Flame Technologies: The Flame Technologies regulator is a modest 580 PSI maximum regulator, but is designed for multiple uses. This regulator is suitable for use with nitrogen or argon gas.

The Kegworks: Kegworks doesn’t provide a PSI rating for this regulator but does note that it is intended for any keg beer delivery systems. This regulator has two gauges that measure in and out tank pressure.

The Uniweld RHP800: The Uniweld RHP800 Nitrogen Regulator is the top of the line regulator and doesn’t cut any corners on quality or features. This regulator has a delivery system of 0-800 PSI, is well built and engineered for an extremely long life.

Regulate Your COfor a Wonderful Aquascape

Natural plants are beautiful, useful, and smart additions to your fish tank.

Fish are happier and feel safer when plants are present in an aquarium and you can enjoy your aquarium even more with a variety of fish and plants, especially if you have a good sense of decoration.

Your aquarium will look like an underwater garden and the water will have more oxygen and nutrients.


This part of the COregulator is electromechanical and it connects with a power outlet.

It allows turning gas flow on and off and it should be plugged into an electric timer.

The bubble counter sends the COthrough a liquid so you can count the bubbles in the system.

Then fasten the small nut again to secure the tubing.

Open the COcylinder and slowly turn the working adjustment knob.

Connect the solenoid to the timer and turn the flow adjustment needle valve to one bubble per second.

You can adjust the bubble counter to the amount of bubbles you need using the aquarium COtester.


The regulator acts as the injection tool which releases pressure from the bottle to a lower and more manageable output.

Usually, regulators will come with a gauge that allows you to monitor the rate of injection and make appropriate changes based on your requirements.

Bubble Counter

The bubble counter is a metric tool that allows you to quantify the COthat has been pushed into your aquarium.

This equipment is usually added to your filter, which then measures the rate of bubbles exported per second.

If necessary, you can use the bubble counter to determine if your aquarium requires more or less CO2.


The diffuser is the tool that inserts the COinto your aquarium.

Typically, the diffuser is a porous material that injects COinto the tank through a fine mist of bubbles.

The diffuser’s main purpose is to equally disperse the COgas throughout your aquarium water so that it is more effectively absorbed by the entire aquascape.

Tubing acts as the connector between your regulator and diffuser.

While fairly straightforward, one aspect to keep in mind is to use tubing that is COtolerant.

Tubing is often not used for the same purpose, so be sure to choose one with the correct properties.

DIY System

There is a “do-it-yourself” method, which involves mixing water, sugar, and yeast in a sealed container and connecting it to your aquarium through a series of tubes and self-made regulators.

This approach, while cost effective, is not recommended for larger tanks; the DIY method would eventually be unsustainable, especially in larger tanks.

Quality design and construction achieves excellence in control.

Needle Valve accurate to one (1)bubble every seconds.

GLA’s new & advanced bubble counter sets a new standard in COregulators. Features built in filtration & check valve to eliminate entry of moisture into internal components of regulator.


Customize the Manifold of the GLA CORegulator. Custom manifolds are built onto the regulator and include bubble counters and needle valves. Supply COto up to six aquariums with one regulator. Installed needle valves will match that of COregulator purchased.

A wetsuit keeps you warm in two ways

Keeping Water Out. Any water that gets inside the suit is going to leak out again. When the water is inside, it absorbs some of your body heat. When it leaves, it takes that heat with it. So the first thing a wetsuit has to do is keep the cold ocean from flushing through it. A good fit, one that feels equally snug everywhere, is critical, so the space the ocean wants to use to flow along your skin is as small as possible.

Some features can help the suit do its job. They include: wrist, collar and ankle seals; sealing flaps behind zippers; pre-bent arms and legs; and smooth inner coatings to minimize water flow inside the suit.


The good news: Among major-label regulators — the kind sold in dive stores — there is no junk. Regulators have been perfected to the point that even budget regulators can offer high performance. However, you must do your homework before buying this vital piece of gear. We can help: Scuba Lab has tested hundreds of regulators in thousands of breathing machine tests. tank to ambient pressure so you can breathe it. A regulator must also deliver air to other places, such as your BC inflator and alternate second stage.

Comfort. Look for a comfortable mouthpiece and have your local dive store select hoses of the right length for you.

Try as many regulators as you can in real -world diving situations. Breathing on a regulator in a dive store tells you nothing about how it will perform under water.

Dive Computers 

Mounting options are an important feature to consider and let you position computers on your wrist, gauge console, hoses or attach them to BCs.

Some computers are conservative in their calculations, automatically building in safety margins; others take you to the edge of decompression and trust you to build in your own safety margins. Only RSD publishes a chart ranking the relative conservatism of dive computers on the market today.

Dive Speak — Dive Gear

Aluminum 80 The most common scuba cylinder, so named because it is supposed to hold 80 cubic feet of air. In actuality, it usually holds about 77.cubic feet.

Annual The required yearly visual inspection for scuba tanks. Also, a similar checkup for regulators.

BC Buoyancy compensator. Also known as a BCD, or buoyancy control device.

Dump A valve used to deflate a BC.

Farmer john Wetsuit pants that extend over the upper body and shoulders (similar to overalls).

First stage The part of the regulator that attaches to the tank and reduces the pressure of the air in the tank to an intermediate pressure.

Free flow An unwanted loss of air from a regulator.

Glow stick A chemical light stick usually attached to the tank valve during a night dive so a diver can be seen in the dark by his buddy and other divers. Also called a cyalume stick.

Mil Short for millimeter, usually used in reference to wetsuit thickness (i.e., a three-mil suit).

Scuba Regulators

Scuba regulators are probably the most crucial pieces of scuba gear you can buy. And, not surprisingly, they are often the most expensive to boot. So before you make that investment, it’s a good idea to be equipped with all the information you need to make an informed choice.

There are tons of dive regulators to choose from so it can be a bit overwhelming. After you read this guide, you should be able to narrow down your choice, making your decision a bit easier.

Diving Regulator Maintenance

So there you have it. Your guide to scuba regulators. While it may seem daunting at first, just break it down piece by piece and see what best fits your needs. Your choice should get narrower and that decision much easier.

Ceramic disc

Gas builds up behind a ceramic disc which has tiny pores that allow a small path of gas to flow through. When underwater this produces COmicro-bubbles or mist, and the smaller bubbles the better as these dissolve more easily.

However, they are fragile so be careful when handling and disc quality can vary from model to model. Some can emit micro-bubbles from only a small proportion of surface area and bubbles can be large. Others will emit a consistent quantity of tiny ones throughout the surface.

There’s no guarantee which you’ll get, so buy several of the cheapest models to ensure that at least one will be good for you.

Ceramic discs are unsuitable for most yeast-based and aerosol systems as will they require a higher pressure.

Clean them by soaking in bleach or a limescale remover weekly to ensure the pores don’t get blocked, resulting in poor or large micro-bubble production.

Inline diffuser

These are becoming the diffuser of choice for many in the hobby.

The gas hose is attached to the diffuser with the micro-bubbles being immediately picked up by the flow and then blasted around the aquarium.

There’s little cleaning required with this method because the device is on the filter outlet and little or no light reaches the ceramics, so preventing any algae build-up.


These are also fitted inline to an external filter, being relatively large and usually positioned inside the aquarium cabinet. They work on the same principle as the inline diffuser, but instead of micro-bubble production the gas is completely dissolved in the reactor. They are usually filled with bioballs or similar to help dissolve the gas.

There are no visible bubbles produced, but many models can restrict flow.

COand your fish

It’s also worth investing in a solenoid if you have a pressurised system. Have it switch on your COone hour prior to lighting and off one hour before the end of the photoperiod. This way the gas should be at a level to promote growth as soon as the lights are on and suitably low when the lights are off.

At night the plants produce COand use oxygen, so observe your fish late at night and first thing in the morning, especially when first setting up a system.

When adding new fish to an injected aquarium consider turning off your lights and gas 2hours prior to addition. This will ensure that the fish won’t be shocked by high gas levels.

Large water changes are the best way to quickly reduce COlevels in the event of emergencies.

Measuring CO2

However, using the table assumes that the only acid in your water is carbonic acid that’s produced from the gas, when many other factors affect aquarium pH.

For this reason another testing method has become popular using a COindicator or drop checker.

The gas reacts with the solution and changes colour according to how much is present.

The aim is to get a nice lime green colour which equates to 30ppm CO2, which is regarded as safe in most situations.

If you have a low-range pH test kit then look at the colour that pH 6.gives. That’s the green you’re after in your drop checker.

Expect to pay around £for a drop checker, £for a low-range pH test kit (bromo blue) and £for some 4dKH water.

Highly recommended product

This is a great regulator. The first one I received was defective (the second regulator did not limit pressure correctly) but NB sent me a new one without any problem. I use mine to either dispense from two kegs or forse carbonate one keg while dispensing from the other. I added a splitter on one line and now can run three kegs in my keeezer; two at one pressure and one at another pressure. Highly recommended dual regulator.

Flag as Inappropriate

I made the mistake of buying one of these a little over a year ago.

I wanted a dual body regulator so I could use one outlet for my kegerator and the other to purge and force carb my kegs.

The set pressure on this regulator creeps up on its own, annoying enough if it just over pressurizes my kegs, but I accidentally left the second regulator set to about 30 lbs. The pressure on that side crept up past where the relief valve opened and an entire tank of COvented off. After my first negative review the manufacturer was nice enough to send me a replacement (thank you).

Unfortunately I had the same problem of pressure creep with the second regulator pressure and I lost a second tank of CO2, this time a newly refilled 20 lb tank. Enough COto possibly cause a life hazard had it been in a small room (mine is in my garage).

Very Disappointed

After days, the pressure relief valves blew out thus draining the fresh tank of CONorthern Brewer replaced the item and sure as shooting, the second regulator had the same issue and losing another tank of COGoing back to Micromatic….


One regulator is extremely sensitive and takes a lot of careful tweaking to get to the desired pressure. The other regulator is apparently defective, I have to twist the knob all the way in to get any pressure, then it goes from nothing to full throttle. This is the most expensive unit I have seen and thus had high expectations. I used a Taprite T752HP in the past and I think that I will switch back to that model.


COwas used for the first paintball markers thus setting the standard for various years on what source to use. When carbon dioxide changes into gas from its liquid state it expands which creates pressure, this pressure is used to fire the paintball via the barrel.

Many COtanks never have to be re-certified or re-tested and are low maintenance. The re-fills are relatively inexpensive and the tanks are compact yielding more shots than compressed air.

However there are some issues, as the liquid expands it also cools and the faster it expands the more rapid the cooling, this can lead to inconsistent shooting. If you ever see white snow falling from the barrel, it’s actually dry ice and a sure sign the liquid is in the gun which could cause mechanical issues.

Compressed Air Tanks

Also known as High Pressure Air (HPA), these are usually pressurised up to the tanks rating of either 3000 or 4500 psi, the pressure is then regulated through the tanks regulator. HPA has consistent pressure and the ability to be used in all weather, accuracy is improved via the higher velocity of the gun with a higher rate of fire.

However there are some drawbacks, if you don’t have a local pro shop getting your tank filled is an issue (we fill these for a cost of £1.00). The tanks are larger and are bulky in comparison to COtanks and they do cost quite a sum more. For a small amount every 5years air tanks must be hydro tested and re-certified.

A Quick Word On Budgets

When you’re buying your first paintball marker you should decide how much you want to spend and there will always be something to fit your budget. The great thing about paintball is there’s such a wide range of markers so there’s something for every budget.

Plus, many markers can be upgraded, so you can start with a basic model and add to it over time until you have the supreme model you’re really looking for.

There are paintball markers for all budgets and they start from as little as £3for the entry level pistols (JT splatmaster / JT ERPump) to way over £1500 for the top of the range electronic paintball markers (Eclipse CS1, Dye M2).


Now, in the next field, let us see the features and the pros of Aquatek coregulator. From the paragraph above, we can see that this product is suitable for a small cobottle, especially for the people who want to maximize the function of their aquarium plants. Here, what make this product special is the combination of its material and design. For the material, it used heavy duty electronic cabling. Also, this mini regulator uses the high-quality plastic combining with stainless steel to provide the durable product. Then, it applies with cool-touch industrial solenoid design.

Then, another thing, which makes this product need to consider is an integrated check valve in the bubble counter. When in the previous paragraph I said about the precision needle valve, here the manufacture also completes it with the kind of the integrated check valve. A bubble counter function to count how many bubbles COper minute which flows into the aquarium. And the check valve to prevent water siphoning from your aquarium and into your sensitive components such as solenoid or regulator. The applying of this feature here is right to counter the bubble. Sometimes, CObubble becomes the problem inside the aquarium, but now it can be treated well.

True Brews

Making Soda at Home: Mastering the Craft of Carbonation. We also spoke with Jeremy Faludi, a sustainable-design strategist and analyst, about the environmental impacts of home soda makers versus store-bought soda. For the science behind carbonated water, we talked to Gavin Sacks, PhD, associate professor at Cornell University’s Department of Food Science.

Anna Perling has researched and written about soda makers for Wirecutter for a few years. She’s a longtime seltzer lover who, before she got a soda maker herself, was known for going through 12-packs of seltzer cans in just a few days. Jamie Wiebe, who wrote our 201review, has written about food and recipes for the likes of Men’s Journal and Eater. She also built a DIY soda maker for our original review.

How we picked

Soda makers work by injecting carbon dioxide into water to produce effervescence. You’ll find a lot of confusing labeling out there when it comes to bubbly water: While club soda and tonic water are bubbly, they have additives for flavor. Club soda has sodium or potassium salts; tonic water contains sweeteners and quinine, an ingredient originally used to treat malaria. Mineral waters can be naturally effervescent or have added carbon dioxide. The Food and Drug Administration defines soda water as carbonated water to which minerals and salts are added, while seltzer is the term for carbonated water with no additives. Technically, a soda maker creates seltzer.

Flaws but not dealbreakers

The Source doesn’t take the larger, 130 L SodaStream cylinders, so you’re stuck with purchasing the 60 L ones more often—but neither does the Power.

Note too that SodaStream will void your warranty if you carbonate anything other than water in its machines. Fizzing beverages such as juice or wine may also cause leaking or overflowing. Instead, to add flavor after carbonating water, you can buy sparkling-drink mix.

The competition

We wanted to check out the Primo Flavorstation, but we confirmed with a company representative that it has been discontinued.

Keurig Kold: The concept behind the Kold was to make flavored soda using pods to carbonate instead of directly injecting carbon dioxide into water. We weren’t impressed with the soda from the Kold, and apparently other people weren’t, either: Keurig discontinued it a little over a year after we tested it.

Bonne O Sparkling Beverage System: The Bonne O, unlike any other soda maker we looked at, uses tabs of “citric acid, potassium bicarbonate, sodium bicarbonate (baking soda), potassium carbonate” to carbonate water instead of injecting carbon dioxide. The first four times we tested the Bonne O, the water was not carbonated and had a salty, sulphuric taste. Although the tabs go into a separate chamber and are not supposed to enter the water bottle, we could immediately tell from the water’s taste that they did. We also found the bottle difficult to attach and the machine cumbersome to clean. iSi Soda Siphon: We tested the iSi for the first two versions of this guide. It ranked the lowest overall among our taste testers in taste, bubble size, and overall fizziness of the water. Cleaning is also hard: To remove an inner chamber to clean the bottle, you need a special tool (and that’s something we’re sure we would lose in about two weeks).


Professional Compact COregulator with pre-set working pressure.

The AquaMaxx Professional CORegulator works great for calcium reactors and COinjection in planted aquariums. Made of high-quality materials, it is designed for durability and works quietly with minimal heat.
