Betta Co2 Replacement Canisters Pack Of 3

Does exactly what it says and is a significant price reduction on the Tropica system I am currently using.

these canisters last for absolutely ages- really good entry level c02 systems

promp delivery,well packaged,reasonable price and good quality

Sadly the dispense nossle is a rather loose fit with my tetra co2 system.Would have been ideal if it were a better fit.

The media could not be loaded. I’ve always wanted to have co2 for my tank but just couldn’t take on the cost of a proper set up so I gave this a shot to see how it would change my planted tank.It’s been about two months of me using this and I am rather impressed! My plants are healthy and extremely green so I can’t complain. Now, I’m not sure if it’s from the co2 or just the substrate I use, but I’d assume both are contributing. It’s extremely easy to use and all you ever have to do is push a button until the unit is full then just repeat when it goes down. I have heavily planted 300l tank and I only have to refill it maybe 2 or 3 times a day. A canister can last me about a month depending on how sparingly I want to use it.My only negative is that I can’t really judge if the proper amount is going into the tank or not so a co2 indicator is needed to be safe.Overall I think this is a great product for beginners to co2 and I’m excited to see how my plants do over time.

Quick delivery.Half the price of a similar product at pets at home. What more can I say free p&p and saving me money.When I need more I will most certainly be re-ordering this product.

Very easy to use and within a week my plants reached the top of my tank very pleased with this product

Got wrong product to begin with but when the set arrived they are great and work really well at a fraction of the price
