Ok guys need a little help again. I have this mystery fine dirt that keeps accumulating on the bottom of the pool. Just ran a complete test here at my numbers
FC 6.5 (before adding the daily dose)
CYA. About 55 raised from 45 in the past week.
I had a similar problem with some algae about 2-3 weeks ago. So I slammed it followed by a dose at mustard level for24 hours. Now the water is crystal clear but I still have this brown dirt accumulation happening. Vacuumed it out yesterday and back washed the filter when finished. Not losing any chlorine over night and total daily dose has been about 2.5 ppm or less daily. From everything I have read that is about normal. The bottom s not slimy and when I brushed it yesterday, nothing visible was stirred up. Since slamming it I know the chlorine level has never gone below 6.5 ppm so I am relatively sure it is not algae. When I vacuumed, I can see the dirt being sucked into the hose through the clear plastic vacuum head. Don't see any dirt getting blown back into the pool but pome how it can not bet rid of it. Not sure what to do to correct. And ideas??? I am going to try and attach a few shots to help. Thanks in advance
