I have not yet turned on my SWG, and have been using 10% bleach from Walmart. Ran an OCLT test last night and no loss. I am keeping my Chlorine target at 7.5-8 while using the bleach. I am adding 24 oz of bleach a day to keep at target range. My CYA is at 60, and I will be raising it to 70 when water temps hit about 75, and I turn on SWG. Water temp is at 67 this morning. Does that amount of bleach added each day sound about right?? I should mention that I LOVE MY SWG, as this hauling of bleach pretty much sucks!! HA
