ok i just hooked up my pressurized co2 system started at 1 bubble per second. and that seemed to be to much. ok quick insite on wut i have im getting ahead of myself. 1 20lb cylender with a 4 waymanifold and choice reg from gla (great btw) and its goin to 4 different tanks. so when i started after about 5-10 mins the fish started comming up for air so i wend down im now at 1 bubble per 20 sec or so. but the thing is that my 55 with the angles are fine the 40 with the goldfish are fine but the 35 and 29 no so much the new african bush fish i got are floating so i removed them and put them in the 55 where they seem to be recovering. and i have all spray bars pointed up to outgass asap. i have read that 1 bps is a good starting point so y did i have this problem?
