I've read the process of adding DE, but have a couple questions:
1 - Mix 1/4 DE in bucket of water. How much water?
2 - Since this is the first time, it says that I might notice a high spike in PSI. I'm at 13 now and it should go to 14 PSI, then I stop adding DE. So, in 24 hours, it could climb higher. How high is too high? Do I backwash to bring it down?
3 - there is some dirt at the bottom fo the pool, water is clear. Should I vacuum before adding the DE?
