Selling a PVC Griggs style Reactor. About 15 inches tall, with hose tails, has screw ends so can be opened to clean. Works 100% perfect, very quiet. I had 2-3 bps with total dissolving of co2, no build-up of gas. Can only post to Australian address. Will take $30, plus $12 post to anywhere in Aus.

I think i am having a co2 problem. im loosing alot of bubbles at thee surface so I would like to get a co2 reactor for my 150 but I dont know any good ones?

I need advice to install an inline heater, CO2 diffuser and UV sterilizer. Now for the details, I have a 70g Oceanic tank, standard wooden stand, Hagen Fluval FX5 canister filter, a CO2 diffuser/reactor that I built myself, a sterilizer that I bought and have never used and what ever heater you...
