I'm a new pool owner (sand filter, vinyl liner in-ground pool) and have never done any of this. I just got the TF-100 XL option test kit. The pool is black and can't see the bottom. There were leaves, worm, green slime, etc. I think I raked most but I can't see the bottom.
1) Before turning on my system what tests do I do?
2) After test which one of the tests do I regulate or do I just SLAM with bleach and make it clear so I can see the bottom?
3) It terms of SLAMming how many times do you do it or do you just keep the levels high until the water is clean?
