My pool was built this year (plastered in June) and I have been doing my own chemicals since about July. The pool water is now below 60 degrees and I am ready to close it. I have hired a company that will put my LoopLoc cover on and close the pool. When I asked them what chemicals they put in, they told me EZPool (but I don't think any chlorine). I am planning to tell them not to put any chemicals in, but want to make sure I know what I should do.
If I understand correctly, I should shock my pool (a couple of days?) before they come. According to Poolmath, I will need 9 1/2 gallons of 6% bleach to get it up to shock level. My FC is 5.5 and I have a 40,000 gallon pool. It looked like shock level was 20 FC. Just a sanity check. Is that right? Do I just dump the bleach into the pool? How many days before they are scheduled to close should I do this? I don't plan on putting Polyguat 60 into the pool.
After I put bleach into the pool, do I need to wait for FC to go down or am I fine having them close it soon after that.
One last thing, when Pool school says add Bleach, I just go to supermarket and buy Clorox Bleach?
Anything else I'm missing.
