Aquarium CO2 Equipment

Discover the range of aquarium CO2 equipment available from Finest Filters, which includes a wide variety of CO2 equipment for planted aquariums. It’s important to monitor the carbon dioxide levels in your tank, with the most consistent level between 15 mg/l (milligrams per litre) and 30 mg/l. Find all of the CO2 aquarium kit you need to monitor your tank’s levels in our collection.

Our planted aquarium CO2 equipment features the Ista Professional CO2 System, which is a great starter set that comes with a variety of accessories, including a solenoide regulator and a diffuser. You’ll find Ista aquarium CO2 equipment such as a CO2 Diffuser Chamber, UFO-style CO2 Ceramic Diffusers, and Mini CO2 Systems for use with smaller tanks too.

Our collection of CO2 equipment for planted aquariums also includes Disposable CO2 Cans, which come in a pack of 3 and are designed to be placed vertically in your diffuser. You can shop Ista CO2 Tablets too, with 100 tablets in each bottle. These aquarium CO2 tablets will dissolve in your aquarium’s water over the course of 2 hours, supporting your plants to grow and thrive. Just one of these carbon dioxide tablets is enough for 20 litres of water - if you don’t have space to store lots of aquarium CO2 equipment, these are a great alternative.

For planted aquariums, we also have a dedicated aquascaping collection, which includes rocks, plants, and other accessories. Shop our full collection of aquarium equipment today, or contact us if you have a question about any of our products.
