I just added another powerhead in my 75g tank, and i was just curious as to where i should put it. I bought it because my NO3 levels were high and i was told that increasing current could bring those levels down. I had it on as high as it would go 680 gph, and it seems like the fish were on a slip and slide of some sort. so i backed it down a little, but wasnt sure what direction i needed to have it or the depth.
can someone please help me?
