Hi everyone, new to this group but my pool is a victim of some maintenance but not to the amount needed, neglect in the winter...
I have a 20k gallon SWG pool. pentair 50 DE filter...
Running my test kit today -
FC - 3ppm
CC - 0
pH - 7.8
T/A - 120
Calcium hardness ~700 (pretty sure this is due to the calcium hypo chlorine used in the pool before enabling the SWG..)
CYA - 90
I have a small occurrence of black algae on a shadowed step, and this morning saw some smaller spots in the deep end...So I scrubbed most of them, but its still there.
So I'm left with a order of fixing stuff, I need to drain my pool both for the enormous calcium, but I'm left with either a trichlor tablet for the black algae trouble spots of just shock my entire pool
Any tips on how to go about getting my pool ready for summer?
