I currently have a Co2 diffuser w/ a hob filter & am considering goin 2 an Eheim canister filter with the ISTA co2 reacter on the "return" line. Any advice. Just set up the tank last weekend & came across the reactor on DFS & liked it.
Go with a danner mag pump with fractioning impeller on it's own closed loop going into the reactor. If you put the reactor on the canister line you will have issues with co2 as your canister starts to clog. Just my 2 cents, I am running needlewheel/ fractioning on both my tanks and am getting the best results and I have tried everything!
