ok I have a standard 75 gall rr with left corner over flow. my return is a spray bar going across whole tank . ( had to face it straight down now cause the waves was making bubbles the bar would come out the water lol. I put the wp40 in right back corner pointing at left front . I hope that's good cause this thing is huge and its not as noticeable in that corner lol as much as a 6 inch power head can be not noticable
