I am getting ready to close my pool for the first time. I was planning to Slam the pool using bleach as described at this site. I have been running my pump and SWG at level 3 for about 8 to 10 hours a day. Using the drops test I found FC = 16.5. Apparantly I should have reduced my running time and/or SWG level when the winter months got here. Rather than adding bleach to slam, I was wondering if I could just max out my SWG for a couple of days and see if I get near the FC = 25 that I need to close for the winter.
Other results from my test today:
CYA = 65
TA = 100
pH = 8.0
water temp = 50F
When checking TA using the TF-100, do you stop adding drops when the solution changes from green to a pink hue, or do you keep adding to try to get to red?
