I completed a SLAM on my freshly drained and refilled pool on Tuesday by passing the OCLT and then did a Mustard Algae Shock which finished Wednesday morning. The pool looks clear and now I need to get into maintenance mode. I took a complete set of tests this morning:
FC - 8.5
CC - 0
PH - 7.8
TA - 160
CH - 225
CYA - 20
I added 4 pounds of CYA 5 days ago anticipating a level of 36 while completing my SLAM. The water tested around 30 since the day I added the CYA. I was anticipating seeing higher numbers as time went on, but now the reading is much lower than before. What should I do in this situation? I am sure the intense sun here in Phoenix will just burn right through my chlorine at that level, but also don't want to add too much.
What else should I be addressing? TA through lowering PH and aerating?
