Product Description

CO2 REGULATOR

Benefits of Using CO2 Regulator in Your Fish Tank

  • Healthy Looking Plant life. A known fact is that fish and plant life need to coexist in balance. The plants thrive on the carbon dioxide that is produced by the fish while the fish feed on plant matter and also take cover underneath. However, too much or too little CO2 will affect both plants and fish. Symptoms of lack of CO2 include plants that have pale leaves and stems, or stunted growth. This also means that the plants will be unable to properly aerate the environment or provide the right nutrients to the fish. Such negative situations are best avoided by installation of a quality CO2 system.
  • Healthy Fish. CO2 plays a vital role in the life of fish. Too much or too little will not only harm the fish but may lead to the untimely death. Fish produce carbon dioxide during respiration. Too much CO2 in the water increases toxicity and affects the pH balance. Unfortunately, unless you are highly skilled in detecting or noticing the level of carbon dioxide, what you will see is sickly or dead fish. A CO2 regulator helps moderate the level of CO2 thus minimizing the negative effects.
  • Combating Growth of Algae. Algae is one of the biggest threats for fish. The compound affects the life of fish by creating unhealthy environment that can cause disease to the fish as well as affecting other plant life. According to studies, carbon dioxide contributes to the growth of algae and also leads to excess ammonia which is dangerous for fish. Installing a system in the fish tank for monitoring carbon dioxide helps combat the negative effect.

Well built regulator for a larger tank and great customer support!!
5 Stars
Well built regulator for a larger tank and great customer support!!
I've been doing high-tech planted tanks for nearly a decade years now. When I bought this unit, I did a lot of research to find the best balance of price, quality, and size. Now that I have the FZone, I couldn't be happier, it is exactly what I was hoping for.Overall satisfaction with product: HighImpression of build quality: HighProduct feels very solid. There is no plastic on it. I expect it will last for years to come.Impression of Needle Valve: HighI’ve used a lot of needle valves over the years, and this one is the best I’ve used. It has fine grain control over the bubble count; and once set it does not seem to drift. I appreciated the inscription showing which direction to turn; as this is a frustrating guessing game on other regulators.Impression of Regulator: HighAdjustment of the regulator is straightforward. Once set; it does not seem to gain or lose output pressure.Impression of Bubble Counter: HighIt looks clean, professional, and exactly like what you want on your showcase tank. Reading the bubbles is straightforward and consistent.Impression of Pressure Gauge: HighThe gauges are large, written in psi and kg/cm2, and easy to read. Having the second 'tank' pressure gauge helps identify when the tank is getting low, that way I have the chance to refill it before it runs out.Impression of Relay: HighI appreciated the quick-disconnect near the relay; as my electrical strip/outlet is not easy to access.Impression of unboxing/accessories: HighThe packaging is what I would expect from a high-quality product. It includes a bottle wrench; which I was happy to have when I needed it. I was also pleased to see an extra set of o-rings was included; no manufacturer thinks to do this anymore.Impression of Customer Support : Very HighI have reached out to Fzone with minor issues in the past. They responded very quickly and were very personable and helped me with my issue. I was very impressed. Just try to get that kind of customer service or product quality commitment from the big guys!Overall, it’s hard to not see that FZone wants to be the best in the industry. If they continue producing products like this and supporting their customers like they did for me in the past; I believe they will achieve it quickly.

5.0 out of 5 stars Seems unbeatable for the price. Works fine out of the box.
Reviewed in the United States on July 21, 2020
Using this regulator with a 5lb tank for my 30 gallon aquarium. So far, it seems excellent. I used a small amount of thread tape on the main connection, the rest was all sealed fine.

The unit is incredibly simple to use, just plug n play, no assembly required. Some people have mentioned the solenoid gets stuck after the first on/off cycle. So far i have not had that issue, ive tested it multiple times today. The solenoid is quiet too. It clicks when going on/off, but there is no hum as I have heard some solenoids will do. I will say, the solenoid is not cool to the touch as advertised. It isnt dangerously hot afaik, but certainly not cool.
The needle valve is easy to adjust and i had things dialed in within seconds.
The unit looks and feels well built. I say its an excellent product for the price point. If I havent updated this post, then it’s still working!

This is my second regulator purchase from FZONE. Super easy to set up - it comes with all the parts and tools you need with a simple instructions booklet.
