Thanks for all the people who keep this site going!
I have a gunite pool that over the winter developed some hard stuff
on the sides. I just had it drained and polished and am starting up.
The quartzscape finish is one year old already.
My difficulty is that it is an outdoor pool with a cover on it. Some of the
pool math is based on recommend FC levels depending on the CYA level.
What level should I use? From research I'm leaning toward 20 ppm.
Here are my startup levels:
Ph 6.6 (should I add borax)
I turned the SWG on with the filter but need to know when to add (how much) salt.
