NaCl H2O,
O.K. I think I have it. I will go ahead and A try to fix any leaks and second lower my pumps. I have about another 3 feet below tank level. I can lower them 2 feet without putting them in an inconvenient place. If not I will think of replacing the pump with a larger one. Is the bubble output bad for Tank? That is I guess sort of a newbie question isn't it?
