What is the lower limit for pH me getting into a pool to work on algae? is 7.0 too low for skin and suits? We have a mask to protect eyes but I don't want to damage lips or skin!
I need to adjust TA and also try to kill black algae spots and I think in view of the short time limit, I will spend a few hours adjusting TA. So I'll push pH down to 7.0 - 7.2 and aerate with a fountain. No time to waste, so we will at the same time be scrubbing the spots with a trichlor tablet. Once I get the TA down a bit, somewhere near to where I can leave it if we run out of time, then we will shock the heck out of the pool for the BA.
I have to be very careful for little kids will be in this pool in 7 days and I only have 3 to do my part of the work. The friend who owns the pool will lower the FC and adjust the SWG when I am gone, hoping that is something she can learn.
