i am hoping that someone on this board is using a fluval 405 fliter and pressurized CO2 .. if so how are you injecting co2 into your AQ..
is it as simple as running the the hosing into the intake of the filter.. but i heard that you lose alot of CO2 doign that.. i want to maximize every ounce of co2 that leaves the cylinder..
