Aquarium Advice Apprentice
I bought a 125 gal All Glass w/dual overflows and a 200 gal. Pro Clear Aquatics sump. I'm using 2 Lifetech 4550 pumps rated at 2650 L/H so i'm guessing there flow is around 650 gph......my problem is with both pumps running the sump level drops below the indicated water line and they start sucking air...i'm using clear hose for my return lines and there approx. 5 ft each...my lfs recommended only running 1 pump but that answer just didn't make much sense to me........any help would be greatly appreciated
