I have a 40 gallon breeder, and have 2 power heads one on each end of tank pointing downwards to the middle they are 550 gph power heads and have 1 240gph ph that points to the surface for water agitation problem is i'm noticing a lot of dead spots in the tank and i've tried switching it up. Is it that i don't have enough flow? was thinking of adding another 800 gph power head?
