Ziss Co2 Diffuser
The ZD-200 diffuser is the new concept of CO2 diffuser that works by tightening the felts.
No more clogging ceramics. So you can easily clean or replace the felt.
You can check and control the speed of the CO² with the integrated bubble counter.
The ZD-200 gives very fine bubbles and can be used in aquariums up to 200L.
