My filter does not seem to work. When I turn it on, after an hour or so there is no water flow, even though filter pressure did not increase. The pump is running fine when I am in circulation mode.
I got new grids last summer, and acid cleaned them last weekend, after which I put 10 coffee cups of Aquapearl. That did not seem to help, so I backwashed a little bit which seem to improve flow for a while, but then I got the same problem again, so I cleaned the filter on Tuesday, and this time used DE.
Same problem again. I checked the impeller (no clog), and cleaned the skimmer, but to no avail. I shocked the pool three times in the past couple of weeks, so my water is blue and I can see the bottom, but it is somewhat cloudy. When I run the robot, the dust comes up. so I know it'snot clean.
Any suggestion what to try?
