I had a little bit of Algae and I hit it hard with Shock. This worked and the water cleared up but a white power is on the bottom of the pool. I put my robot in and half the powder is flowing thru the robot filter. I suppose my pool filter will get some and some will fall back down. Do I just keep doing this cleaning both pool and robot filters until I'm done? or do I use a clarifier to make the particles larger?
