photo.jpgHi. My water is clear but I have what looks like algae staining the bottom of my pool. Please see attached photo. Since my water is clear, do you recommend a complete SLAM or is there another alternative? And if I do SLAM it, what is the max Cl level that is considered safe for swimming?
Here are my test results:
Taylor K2005 test kit.
Updated: I just swept the pool. There is a small grey/green/brown cloud that comes off the bottom when I sweep it.
