i got that bolt in last week. not as much sand/DE in the pool as before but still some. i don't see any rips in the fingers at all. pH went down to 7.2 added more borax went up to 7.8. sparkling water. have been able to keep FC around 3 with adding 1/2 gal bleach every other day. I'm ecstatic with all the help I've gotten here. just wish i had more time to work on pool or come on here. work and kids are keeping me extremely busy
