Wow...this is a delicate dance between FC and green !!!...As of this morning, Water is finally holding FC overnite, but the metals fell out again...The ONLY thing I did different was to shut down the filter last nite.....Does pool water with metal issues need to be pumped 24/7 ?? I turned the pump back on and i'll see if the stains dissipate
