Well I did my opening today. Closed following TFP guidelines, and I opened to crystal clear water. Here were my numbers after two hours of running my pump prior to adding anything.
FC: 2.0
CC: 0.0
PH: 7.2
TA: 70
CH: 190
CYA: 60
Temp: 47 degrees
I had very little leaves in the pool. The polaris had it looking like it does on any given day in the summer in a couple of short hours. I gave the floor and walls a good brushing. Brought the level up to slam. Once the water warms up more I will switch on the the SWG. I am sure I will need to add some salt prior. I will test for that closer to that time. I'll check in a few hours to make sure my FC is holding. Once the level drifts down I will do a OCLT.
Here is a pic just 3 hours after open.
