A simple diffuser and a reactor for DIY CO2

Setting up my fish-room and adding several aquariums, all planted and with DIY CO2 from centralized unit, I needed several diffusers/reactors for them. I tried all the reactor designs available, just could not fit them into the space available and as I use UGF and not canisters I needed reactors for my larger tanks.

I got to experimenting and ended up with a very satisfactory and simple solution.

The diffuser is a ¾”slice of 11/4” pipe with an air-tube from the side and both faces stuck with discarded membrane of my RO and packed with filter floss. This produces quite satisfactory micro-bubbles at very low pressure of DIY CO2. Putting it near the spray bar of my powered UGF is sufficient for my smaller tanks.

For the larger tanks I using a power-head with a ½” elbow stuck to the output and pointed down, and I have stuck a 500ml. pet bottle (with bottom removed) and fitted my diffuser inside it making a hole for air-pipe in the elbow, makes a very efficient reactor.

My 250G uses two of my reactors with 1.5L bottles instead of 500ml bottles. Everything working satisfactory.

If you have a choice, you have a problem, till you elect your choice. No choice, no problem, only consequences, learn to live with them.
