New pool owner; had a basic question. I have a SWG system in my pool. I had to add 14000 gallons to my pool because it leaked out. Got the CYA up to level; added salt and got up all the other readings near or into the right range.
However, yesterday I had a reading of 0 FC. I have put in Liquid Chlorine and started my SWG and set it to 50% output. But why should I go for a shock FC of 24 with a SWG system and a CYA of 60? If the water is clear and there are no problems why wouldn't I raise the FC to 6 or 7, why go so high as 24?
