I have a 24ft agp...For the past week I have had a problem with sand...it was sand initially...I picked it up and felt it in my hands...it was grainy and did not disintergrate in my hand. This weekend I noticed that after a couple days of vacuuming up the sand every day...it stopped coming back. Now I have a brown powdery substance on the bottom of the pool. I vacuum it up, and the next day it is back all over the pool in the little wrinkles on the bottom of the pool...This is my first year with a pool...The water sparkles all the time...It has never been cloudy, and I keep the pool at about 3-4 ppm all the time...PH holds at 7.4 to 7.6, hardness is 170 and alkalinity is 110 ppm. My CYA is probably a little low...just retested it and it is about 25. I add 36-50 ounces of 10% clhlorine every couple of days...the past week has been extremely hot. Last week we had two huge cloud bursts. On Thursday we had enough rain to bring the water up over the skimmer...just filled to 2/3 of the skimmer plate...so it was up at least two inches...I have trees on three sides of the pool, but the pool is in the sun...Same thing happened on Friday...both days I had to drain water off of the pool to bring the water down to skimmer leves...Could the brown dust on the bottom be pollen from the trees. I notice that when I vacuume and the skimmer is not running the surface of the pool is covered with a dusty substance. Is that tree pollen that then sinks to the bottom and rests in the wrinkles and divits in the liner???
Chlorine seems to hold very well. Although I need a better test kit...I do know that I do not show CC's
The water does not seem to be a problem...I think I might take a dip and try to suck some up in an eyedropper and look at it...
