Bc of my leak that I can't find, I'm always struggling with losing/adding water. So it makes me cringe when I backwash and watch all the water pouring out. This makes me wonder if maybe I haven't rinsed all that dead algae out bc I only run it on rinse and backwash for seconds, not minutes. But the water in site glass is not dirty so didn't see any point in wasting my water. However, maybe I should rinse and backwash real good once to thoroughly clean filter? What is the "proper" way to do it? Turn hand to left until it says rinse, run 1full min, turn handle even farther left to backwash, run another full min, then turn handle back to the right until back in the filter position?
