First post, was getting ready to give up on my stupid pool forever before I stumbled on this site and discovered my CYA of 150+ was probably part of the reason my pool was unmanageable. So I did a full drain and should be done with my refill in a couple hours here. I have 9 gallons of clorox in the garage, 3 boxes of borax, 2 gallons of murietic acid, 2 gallons of conditioner, and a new fancy test kit. So hopefully I will be ready to keep this thing in top shape going forward.
Before I drained my pool I was having a major algae bloom I have been fighting for 2 years. (Its hard to get a decent shock when your pool has a 150+ CYA!) So when I drained it i sprayed the walls with bleach and scrubbed them and let the intense Phoenix sun beat down on them for a couple days. But I am still worried there could be algae hiding somewhere.
Question 1: Should I go ahead and bring my FC up to shock levels right away?
Question 2: Considering the amount of sun I get, how high should I set my CYA? I got liquid conditioner so I can change it quickly.
Question 3: What order do I add all these things?
Here is the test from the pool on the fill water:
FC - <.5
CC - <.5
pH - 8
TA - 140-150
CH - 250
CYA - 0
