Yep, another one of these posts.
Have been using TFP this year and beyond happy.
Today we swam and our eyes burned the rest of the night.
First time ever.
Figured CC must be high or pH out of wack.
CYA still 50
so I guess I will test in morning as a OCLT.
Can't think of anything else.
Had wicked storm last night and cleaned green leaves this evening.
Pool is clear.
