This is the first summer with our pool. Last couple days water testing have been very consistent....haven't even had to add acid to lower the pH.
My question is about how to lower the FC. I know it's safe to swim and all but it really doesn't need to be that high I don't think. We haven't been in the pool yet because the water is too cold (no heater, yet), 72 deg. So I'm trying to figure out my pump run time with the SWG %. We have pump set for 12 hours on, 12 hours off. I had SWG at 40% three days ago, and each day I would lower the percentage and tonight after testing and seeing the FC was STILL at 11 (for the last 3 days), it's now set to 0% and I will test again tomorrow evening. Would it make sense to just shut off the SWG until the FC level drops? Using the TF-100 test kit.
