After several Shock Treatments, we sent out Route Manager extraordinaire, Jonathan Turner to check on the Customer’s green pool. He noticed there was something not quite right about the circulation system and decided to disassemble and inspect the Diatomaceous Earth filter. The problem became immediately apparent, a mass of dirt, leaves, debris & D.E. bridging the grids causing no filtration to occur. Per manufacturer’s recommendations, these filters should be cleaned & inspected minimally once per year! Problem solved! Clean & Blue! Happy Customer! Call for D.E. Service only $150.00
