Finest-Filters Ista Waterplant CO2 Diffuser Set System Growing Live Fish Tank Aquarium Plants CO2 For Plant Growth

Simple and effective entry level co2 system that delivers results without breaking the bank. I've been using it for a while now in a ten gallon planted aquarium and it makes a very noticeable difference to plant health. Great product if you're looking to see what co2 supplementation can do for your tank without investing a lot in more complicated systems. The downside with this is that you have to fill it up every day but it's easy enough by just pressing the cap on the co2 can. There's also the fact that the composition of the gas in the chamber gradually changes because as the co2 diffuses into the water, oxygen and other atmospheric gasses also diffuse into the co2 chamber reducing the proportion of co2. This means that you either have to overfill the chamber slightly so that the remaining gas is displaced by the addition of more co2, or purge it daily/every other day by opening a small valve at the top of the chamber to release rhe remaining gas before you refill it. 5 stars because it's cheap and does what it claims. It's not perfect but it's good for the price point.

Great kit, super easy to use. Initially I was concerned because the co2 tank is so light that it feels empty but it lasted me 6 months in my 120l medium flow tropical aquarium

What I found simple and easy is , any one can use this . I bought it for my guppy tank and it is 25 gallon and im very happy with product . My plants looks very fresh and healthy . Only using for a week . I definitely recommend if someone has smaller tank 25gallon to 50gallon . I have never tried bigger tanks if I use it I’ll definitely share here thankyou . All three pictures has taken on day one when I started Co2 4th and 5 picture this is after month of co2 .

Recieved on time and well packaged. I know this is cheap as chips but if you want a c02 set up, spend abit more money and get a good one. This one works but the pipe is only long enough for the can to sit at the same height that the tank is on, also the diffuser part really does need some sort of gauze or netting on the bottom to stop fish swimming inside and getting a massive dose of pure c02, my ghost knife fish went straight up into it as soon as i put it in. I wouldnt leave this unattended in the tank just in case.

I’ve had this system set up for a few weeks now in a tiny 17 litre tank. At first, I was expecting that my plants would grow uncontrollably and I would be cutting them back all the time, but that hasn’t happened. What has happened is that my plants do seem to be growing a little quicker than usual,but more importantly, they are growing more healthy, no more plant melting,they’re not dying off. If you have a small planted tank I can certainly recommend it. I top it off every day or two,and so far I am still on the original canister. This is an ideal C02 starter kit before spending more money on a more complex system.

Neat little system, very basic and simple to install. Great starter kit 👌

I received this Finest-Filters Ista water plant CO₂ diffuser set and have been testing it in my planted aquarium. Setup was straightforward, and all the parts feel well-made and durable. Once installed, the diffuser produces very fine bubbles that dissolve well in the water. After using it for a short time, I noticed healthier-looking plants with better growth and color. The system runs quietly and does a good job distributing CO₂ evenly throughout the tank. It also looks clean and unobtrusive inside the aquarium. Overall, this is a solid CO₂ diffuser set for anyone maintaining a planted tank. It’s effective, easy to use, and does exactly what it’s designed to do. I’m very satisfied with how it performs and would recommend it to other aquarium plant enthusiasts.

Canister arrived empty and clearly already had been opened.
