Hi all! I'm getting back into the hobby and ran into a issue regarding my return pumps... So I have a 375g tank and currently have 2 BlueLine 40HDX external pumps that were recommended to me from my LFS so I went with them... Come to find out according to several other enthusiasts that these pumps aren't sufficient GPH for my tank. Was even told to just go with a cheap aquastation dc12000 pumps which have a suggested 3100gph each compared to my 1400gph and so ditch the AC pumps.... So with all that being said, input is greatly welcomed!
