Will it do any harm to drain it down and super bleach it? Maybe 20 gallons or more? I figured that by draining it quite a bit, a more concentrated bleach level will be getting to the algae because it won't be so diluted. I don't want to eat holes in the liner, though! I'm keeping the chlorine in the bright yellow/orange, and we have 3 tablets in the basket at a time. This is our first "real" pool that didn't come from Walmart and all this is rather new to us. I need to hear from an expert what they would do? Preferable someone who is not independently wealthy☺
