I vacuumed using my leaf bagger/hose. This generated big white clouds making it impossible to see the bottom. The water was clear when I started. In the past my crawler has picked up small white crystals also.
My CH is on the high side and I recently replaced my DE filter elements which had numerous holes along the edges.
What is this stuff? I'm going to let it settle and vacuum through t6he filter tomorrow in hope of getting rid of it.
