I did some heavy construction on a patio adjacent to my pool last month, and demo'd a lot of saltillo tiles. Unfortunately, a lot of that dust went into the pool and spa. The spa is closer to the patio area, so it got a lot of dirt/dust in it. I have a Hayward poolvac for the pool, and it seemed to survive pretty well.
I completely cleaned my filter last weekend, and the grids held up OK, but I still have a lot of debris in the spa. Any suggestions for cleaning the silt/saltillo dust out of the spa, without ruining my DE filter again? I tried a little sump pump I had from my pool cover, but it didn't work too well. I guess I should have used the pool vac in the spa BEFORE I cleaned the filter again, but kinda forgot.
Any suggestions on how to clean the debris out of the spa?
