Hey friends, starting the pool up and needed help with the order of doing things. I know I already have an algae problem (not too bad) but when I tested I realized the cya is probably 0. Here are the numbers.
So, do I start shocking tonight with bleach or do I need to raise the cya first? I have seen on some posts that if I use dichlor it will raise chlorine and cya at same time. I have never used that before, only bleach. Is it something available at Wal mart or just pool stores? I have the bleach ready to go. Also, because of the algae, I am sure I will be backwashing often and thought that was a no-no when you had added chemicals for cya. Just a little confused. I appreciate the help!
