My name is Seamus ( Irish for James )
Live in Sacramento Ca.
Pool went Black Lagoon last Fall, emptied except for the last foot since then.
So tired of the chlorine battle installed SWG.
cleared out remaining water, disgusting.
Fresh Water, 600lbs of Morton Pool Salt, Shocked with liquid chlorine,
Two hard weeks of testing, chemicals, running the pump, clean filter again.
Pool is crystal clear.
Still need to pumice the sides, but I got some time.
Need a little more CYA, SWG working good. Three hot days no change in chlorine level
Thanks for all the great info, going to do the BBB.
