I have to vacuum the complete bottom every 2-3 days - very powdery dirt/dist settles to bottom and covers in a brown film. First started happening during first week of July here in St. Louis - multiple weeks of 100+ degrees. I live in a new home development where there has been non-stop construction digging foundations, grading, etc. on about 10 large home, and, until this past week (due to remnants of hurricane Isaac, very little rain).
The water is clear (from a distance), but once in the pool, lots of crud on surface and suspended in the water can be seen with goggles underwater. Vacuuming has been stirring up some of the bottom.
I test my water with a Poolmaster Basic 5 test kit and once a week at the retail store for the company that built the pool.
Is there something chemically wrong in my numbers? Total Chlorine 5.9; Free Chlorine 5.9; pH 8.2; Alk 130; Calcium Hardness 75; Salt 2900. I ran my Goldline Aqualite system on Super Chlorinate a day before so my Chlorine is high but will be on its way down.
I backwash for 2 minutes and rinse for 1.5 minutes after each vacuum )my pressure gage never goes above 20psi. When I close down the other inlets to drive all the suction through my hose for vacuuming, the filter shows 15psi.
Is it possible that I have some type of scaling or just that much dirt in the air?
Appreciate any help you can give me. I had a pool service come once a week last season and this season I took over. However, no houses were under construction last summer near my house and there were no drought conditions like this year.
I also wondered if the potential added load of the dust and dirt is overwhelming my filter's capacity. While the design rate is 98GPM, I believe that the pump is generating closer to 50GPM at 1.5HP and what looks like a 1.5" pipe.
