## Description

DESCRIPTION: Clscea CO2 Diffuser optimizes the CO2 entering the aquarium for efficient plant absorption and less waste. As CO2 bubbles pass through the porous diffuser, they are diffused into streams of tiny bubbles. NOTE: It is normal to have large bubbles at the beginning. Soak the diffuser for 24 hours inside the tank before use. Please do not wipe the ceramic plate or clean it with a brush, it is easy to cause clogging, please use special cleaning products. Not suitable for low pressure DIY plastic bottle generator. PACKAGE INCLUDED: 1 x CO2 Diffuser 2 x Suction cup 1 x Anti-slip rubber ring

### ⭐⭐⭐⭐⭐ Review
*by R***Y on 5 August 2024*

I've been using CO2 systems in my aquarium for a while. Typically opting for the plastic with cork diffusers, while they do the job they typically have leaks and from my experience become hard to upkeep with appearance. I decided to pick up CLSCEA stainless steel diffuser and it's a gem. Easy to install the connection points have a check valve and tube lock that ensure no CO2 leaks. I'm sure ovee time the ceramic plate will have algae and require some cleaning/replacement. But overall I really love the look. It does give the tank a little modern look so might not be for everyone but I think it really is a nice add.
