I could really use some help.
I currently have a 10k gallon green pool. (photo attached) Normally its very blue and looks great.
This all started Friday night, had high ph 8.1, and almost no chlorine, So i turned up the Jandy salt cell and added some acid to bring it down. By Sat morning water turned green, but not cloudy. Cannot see any build up of algae on any surfaces except one spot at water line in hot tub, it was about the size of half a crayon in the grout.
Reason perhaps ? No chlorine .. I looked at the Jandy readout, it said 3400 ppm salt.
Had it tested several times Sat morning, pool stores showing it at 2200 ppm salt.
So I assume from having low salt, and the salt cell thinking it had 3400 ppm = no chlorine being made.
So I have the salt cell off for now until I can have it looked at.
I have been using bagged shock for the last 2 days, and have kept the chlorine high, 3.5 lbs used so far.
I have tested the water at home and Sat had a few pool stores check it, it was right at 5 ppm, which is exactly what my test kit showed. The chlorine/ph tests on my kit has been remarkably accurate. I boosted it more Saturday Noon and kept in the orange on my test kit.
Scott PoolguyNJ told me to post these numbers.
Alk 100 ppm
CH 220 ppm
FC 5+ ppm (photo of test attached, it only reads to 5 ppm, but indicator is dark orange so I am guessing lots of chlorine.)
TC 5+ ppm
CYA 100 ppm
TDS 100 ppm
Salt 2200 ppm
phospates 800 ppm
iron 0 ppm
Additionally I have found out that some fertilizer may have made its way into my pool on Friday, I found a small amount consisting of white, black and green granules in the Polaris bag, which i have removed.
Also my Polaris and white fixtures in the pool like drain covers are taking on a tan colored sheen that will not wash or brush off. ( Photo attached) and there is a similar discoloration around pool where the water meets the tile. that does not scrub off.
I would appreciate any assistance. I am concerned this may not be algae? I have had the pool high in chlorine for 2.5 days and the pump running non stop and it has not made a change at all. I have also been brushing 2x daily.
Any help sincerely appreciated.
