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.

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.

Great little tester kit before I go all in for a full co2 set up beware co2 can dose feel empty but it's actually full easy to set up and use I have a 300lt aquarium so will be interesting to see what results I get after a month will update review in mouth time but so far really impressed

This is the easiest co2 system I have found. The only drawback is that the suction cups on the chamber harden quickly and come away from the side of the tank. It would be good if they provided replacements in the same pack to help overcome this as stand-alone ones don't always fit well.

Easy to set up and work, only a week or so in but seems to be working well, I have also ordered some more cans

Goes with dodgy canisters.

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.

This review is for a 30 ltr tank: So I was really scared using it cos I have a fear with cans filled with pressure but when I started using it I got habitual but I still am scared to hide it behind the tank hence the can is on the floor. I can manage with a little bit of mess rather a pool of water in the house and my dead fishes. Things I liked: It's affordable- considering the other setups it's quite cheap. No co2 overdose- this is my first time using CO2 for the tank I was sceptical to disturb the ph and what not did my research what amount is ok for the livestock but still I'm careful. Therefore it's nice I can handle it manually. In the morning I inject and it goes on for almost 8 hours maybe(very slow dissolving) which is fine for me. Results- Before injecting I wasn't seeing any bubbles in my tank and after 10 15 days I started seeing plants making bubbles. Loved watching it. Since then I have trimmed my plants. The best part is my Christmas moss just loves it and thriving far better thank before. And yes also with a little injection there is no algae as I heard it can be a cause of it. Cup dissolving method- you know that when you put an air stone in the tank and the bubble just pops up at the surface I always wondered if there is any dissolving happening. Obviously the CO2 diffuser atomises the gas which dissolves more than an air stone does but still. Here, in the cup dissolving method where the mixing happened layer to layer it's actually better and the CO2 has to be dissolved in water before the cup needs another round of injection. This is atleast what I think it is and I know I'm not wasting much of my gas and the can might go beyond my anticipation we'll have to see. Things I don't like- Diffuser- it's huge, I mean although it's behind the plants but I don't want a huge cup sitting in my tank considering it's already a small setup. Manual control- it's funny that I just talked about how I have a control but when you have to inject CO2 one hour before the lights are on in the morning it's a JOB and you have to do it before your coffee or loo. But as long as my shrimps are happy I can sacrifice a little. Also, I inject the gas twice. Once at 7 am and another at 4 pm, you'll figure it out once you are accustomed of it and how much your tank needs. Coverage - I have heard that the atomisation (bubble diffuser) helps CO2 move around the tank but I think with this method the concentration would be at one side more than the other considering the filter is set to the lowest hence the water is not moving as rapid. Over-all as long as I'm at home I don't mind this set but would I change if I don't stay at home ? Of course I will. But I'm happy with my purchase as for now.
