| | Re: Tiny super efficient CO2 reactor
This is awesome at diffusing CO2 in my 29 gallon. Instead of placing the sponge on the outside of the flow nozzle, I left the majority inside and cut a small enough piece to fit inside the nozzle, between the impeller and output. This was done because I wanted to maintain some of the flow created by the filter, as I am currently using just a HOB. It is not as efficient, but it is now performing 3 duties for me as a filter, CO2 diffuser and mini-power head. Great DIY!
