Just picked up a botttle of Odorlos. Added 2oz and about a gallon of water to a nearly empty 20 gal tank. The instructions also say to dump and rinse weekly. Using the boat only on the weekends we normally pump out about once a month. is the weekly pump out necessary? Seems like a waste of chemicals if I'm treating a 20 gal tank but pumpng out at 5 gals or so.
