Hello,
Ok do here's a dumb question, being that I come from the freshwater side of things, and new to saltwater, I added a check valve on the out tubing from the aqua lifter for ATO, ( thinking air line for freshwater) and noticed that water is still in the tubing line coming in to the pump and also the out tubing, is this normal or am I missing something here?
