The heat pump on our pool has been leaking and the plumber has spent the last three weeks trying to locate the part needed to repair it. Because of this, our pool pump has been off for three weeks. Since I use the BBB method, I've been able to keep the pool relatively balanced, but am worried about the water that has been just sitting in the pipes, pumps, and cartridge filters. When I remove the filters for cleaning tomorrow, should I soak them in a bleach mixture, or will just running the pump with the chlorinated pool water through it be enough to kill everything that I suspect has been growing in there? I've raised the chlorine level to 21 (my shock #).
