1. Water all in, I have shocked it tonight again. I have yellow looking stains all on the bottom. How do I get these out and with what? The pool is a white fiberglass.
I did a test tonight and the PH was fine but had no clorine. So I shocked it. I forgot all about getting tablets to get in pool so I will get those tomorrow to keep the clorine level up.
Now..what is the acid for? What is the purpose in the acid?
Now on the stabilizer...Do I add that right after shocking or best to add the next day? And do I just throw it around in the pool or pour into skimmer?
Any help will be greatly appreciated!
