hello everyone, ? i have a 75 gal long with a 20 gal sump. do you change 20% the total 95 gal or 20 % of 75 gal. what i have been doing is turning off the return pump letting it drain into my sump then draining it and my built in overflow. one more thing i just got a 2bulb t5 lamp that i was told i may be able to keep a few soft corals. what do you suggest.
