I do not post much, since I usualy search and find answers to many of my questions. But first, I wanted to give thanks to everyone who takes the time to answer and help us new pool owners.
I am having some staining issues. At this time, I am trying to determine if they are organic or metal. Unfortunately my work schedule and the weather here in Galveston, Texas, has not allowed to me give 100% attention. We are having rain daily, sometimes a light drizzle to the, out of the blue, 10 minute downpour. I plan on taking next week off (not a vacation, but a big honey-do list) and tackling the pool staining issue is a priority. So everyone will get to know me real well then.
Anyway, my question is regarding the overnight FC loss test. My pump runs from 8 AM to 8 PM. So the pumps are completely off overnight. I have done a couple of preliminary loss tests to get the hang of things and I am showing some loss (1st test 1.5 PPM, 2nd test 2 PPM), but again, both times included an overnight rain (not hard enought to wake you up, but I can tell by the small water pools on the deck). Is it safe to assume the rain could have contributed to the loss? Also, should the pumps be running overnight to keep the chlorine circulating?
I apologize for the long winded post, but I am actually preparing everyone for the barage that will be coming next week.
