Quick question. Need to know what pump size and bulkhead to order. Tank is a 10g AGA with overflow box dumping to 10 refug. Tank will need med-high water movement, just dont want to pressure wash anything inside tank with the returns. Bout 4 ft of head and can use submerseable pump if needed. Should I be getting the 3/4inor the 1in bulkheads?
Thank
