high water level in wet dry sump
I have a 250 gallon freshwater aquarium w/ built in overflow and wet dry sump.I'm using a little giant series 4 in line pump, and I have a separate pump running to an ocean clear canister filter. It's plumbed with PVC pump.The water level in the sump keeps rising over a period of two weeks. I don't see any obstruction on the outflow side of the pump. Any ideas?
