Being a newbie to pools, I don't know what normal cleaning maintenance for a pool results should be, if dirt should show up after a brushing etc. I can't figure out why our pool is still so dirty.
Our water is crystal clear, until I brush the pool or run the robot. After that it is cloudy and I have to run the filter overnight to get it clear again. When I brush the sides of the pool, a brown dust-like cloud comes up - also in areas of the floor of the pool (you can't always see it until you brush it up). It seems to accumulate in the same areas (near the steps, under the returns and along the bottom where the shallow end starts to go deep) The dust/dirt has be present even after running the robot through 2 cycles (6 hours) in the same day. The filters on the robot are usually filled with a sand like dirt. I have run the robot 6 (in 2 weeks) or so times and I brush the pool about every other day (if we want to swim) if not daily. There are areas in the pool, once the pool water is clear, that look like dirt has settled. It goes away after a cleaning but then is back usually the next day.
I have been maintaining my FC (4) for my CYA (25-30). I have increased my CH to 250 since it's a gunite/plaster pool. PH, and Alkalinity are all good. CC is at 0 and the overnight test was a .5 loss this morning (I tested in a shady spot since the sun was just starting to get to the pool). So I pass all the requirements not to SLAM. So, if I don't have an algae issue then what is all this stuff? I know Divin Dave said the pool could just still be this dirty still from the SLAM, but even with all this cleaning the walls are getting it back. I brushed twice today, once in the morning and just a bit ago tonight, as the dust/dirt was coming off again (I also ran the robot twice today).
Any ideas or experience with this?
