  • Produces Small CO2 Bubbles
  • Made of Break-Resistant Acrylic
  • Easy to Install

This CO2 diffuser from Aquario is one of the best on the market. It features a small, brown ceramic disk which does an excellent job of breaking down CO2 gas into the finest mist of bubbles. The finer the bubbles, the better the CO2 can dissolve in the water and therefore plants have an easier time utilizing the CO2.

The other great part about this diffuser is that it's made out of break-resistant acrylic as opposed to glass so it can very easily be attached to tubing without having to worry about smashing it. Suction cup is included for easy installation. We've found the large size diffuser to work in any aquarium and as such, we only carry the one size. Co2 pressurized gas system required to utilize this product.

Works as described

Puts out very small micro bubbles that are dispersed in the water for the plants.

As always, great product for the Co-op!

Great all around diffuser for the price.

This is my first diffuser , I’m currently using it in a 20g long . For a budget diffuser it’s getting the job done fine. I will be upgrading to an atomic diffuser soon but that’s only because this tank is pretty shallow and I think I will be able to reduce my bubble rate with an even more efficient (but way more expensive) piece.

Aquarium CO-OP the best

I have received nothing but the best from them.
The CO2 system helped a lot and was really easy to set up.

Best Diffuser I've used to date.

The title says it all. Ordered a second one 2 months later so I can swap out for cleaning. Recommended!
