My water is clear 2 days after opening, but I have some algae sitting on the bottom and sides of my pool. When you vacuum to the waste line, does it have to be 100%? I ask because it dumps so much water, I feel like I really have to hurry otherwise I'll dump too much water.

I figure I could close 2 of the 3 intake lines (2 skimmers and the drain) OR adjust the 3-way to send some of the water back to the pool.
