I am planning to open up my pool this weekend, and just wanted to run down the process that I am planning to use. This is my first year with a pool, my wife and I bought the home from the owners who originally put it in. They left some chemicals behind, including an inline chlorinator and a "Pool Frog" mineral cartridge, they also have a 25lbs jug of Calcium-Up. I don't have the cover off yet, but I have peeked under and the water looks pretty clear, I can easily see the bottom.
My process is going to be:
-Removal of cover and set up of equipment.
-Test water immediately
-Start pump and let run for 24 hours over multiple days
-Adjust PH and SLAM if needed
I want to test the water right off the bat to see how much CYA is in there. I'm not sure how the pool was treated, and I'm a bit worried they just used chlorine pucks, so my CYA levels might be high. It appears as though they drained the pool about half way, a good 3-6" under the skimmer.
The pool is set facing NW, and is in the sun from sunrise to sunset. I was thinking of starting at 50 CYA to help offset FC loss.
