Would 30 ppm Chlorine burn off particulates?

Thanks, all, for your help.

I hosed down the cartridges and a LOT of silt came out. The pressure went down to 15 psi, which is normal for my system after cleaning. Brand spanking new cartridge = 13 psi, normally I clean at 20 psi, this heavy algae/scum removal project took it to 35 psi which caused all the other problems. Now the ray-vac calmed down, the skimmers work, water is flowing from the spa to the pool, all is well.

The pressure rose even while I adjusted the water (added 1c acid, more sodium hypo, and 3 trichlor pucks) so I may have to do this a few times this week. Small price to pay for getting my pool back. Besides, with practice I am getting much faster. ;-)
