I'm having some pitting problems with my plaster, and the pits are gathering alge.
Trying to figure out why it's pitting like this. Getting worse.
The pool was replastered 5 years ago.
My PH always runs high and I use acid every few days to bring it down.
CH is 200
TA is 80
PH is 7.6 today
Water temp 77f
Been using bleach in pool for 5 years and water always looks good but I do get these algae spots in the pits.
