last week, my tank grow slime algae so i used red slime remover, and it's gone this week. Today i changed 20% water and also i decided to put in a seio 620 in and add one more powerhead with the tube with 5 holes pointed up toward the light. i wonder if this set up will help my tank stop growing algae and safe for the fish. seio is 620gph and other one is 1100gph.
