Its been super hot here and to shed some power usage I've been limiting my pool pump run time. The pool water is suffering, usable but not sparking clean. I found this on Amazon awhile back. I will be knocking one off, this weekend if there's time. I already have a 20 watt panel with a charge controller and small pool filter, just need a $20 bilge pump.
