Rioduo

looking for ideas how to cleanup Inground pool after river flood. I have a large amount of sand in bottom of pool and hoping I can get some idea's on ways to cleanup pool. I have a DE filter, but would like to minimize flow through filter since it would take no telling how many cycles to clear pool. I live in the Houston area, so if anyone knows of a rental place that specializes in temporary pool filter equipment I would really appreciate the help. Thanks, James
