Losing almost 5 ppm per day without anyone swimming is too much.Thanks for all your help. I raised it yesterday morning to around 5.5-6.0 and when I checked this morning it was 1.0. Is that normal? I feel like I am dumping loads of beach (little over a gallon) in everyday to keep the level. No one used the pool yestetday. Full sun, outside temp in the high 80's around 90.

Then do the full chlorine test with the powder and let's see what the CC level is. And plan on performing an overnight loss test tonight.I have the Leslie's fas-dpd test kit

overnight loss test.OK. Think I figured out the problem. There was a small amount of algae on the wall right under the top rail (all the way around the pool). The water was splashing up on it. Would that cause a dramatic drop in FC? I brushed all of it about an hour sgo.
Any best way to proceed?

For your daily maintenance if you only plan to test once per day, it should be in the evening after the sun is no longer hitting the water. This allows you to adjust up to the recommend level if needed and have it be effective all night.
