Thinking about going with the Sera Flore 500 Co2 reactor from Petco. I think it would be better thanks the Rhinox diffuser I bought. I read some good reviews on it and it's on sale at Petco
I have a Sunsun HW 304b and it's rated at 525 gph. The Sera Flore reactor says you don't need a lot of psi like some of the other models so I figured it would be a good one to get. I also figured I'd get a 20lb tank and then see if I can find a place locally to swap out periodically. We have a bunch of welding supply stores so I should be able to find a good place!
