High CH vinyl liner

[michelleca]

I'm having a problem with slightly green tinged water in the deep end.
FC <.5
TA 130 (added muriatic acid to lower)
PH 7.6
CYA 41 (added stabilizer to raise level)
Salt 3400ppm
CH 455 (I only know this because pool store tested water, I never test for CH)

I can't seem to make chlorine. I had SWG raised to 75% and still only have less than .5 FC. I turned SWG off and added a bottle of bleach, but pool is still tinged green (I haven't test FC since adding bleach about an hour ago).

I've also noticed some rust spots on the liner. Could high CH be causing the rust and/or the green tinge? Not sure why I can't raise the FC though. I have a gas heater. Pool store said high CH could cause rust on heater, etc. Not sure I believe anything they say.

The reason you can't keep your FC up is because you have algae eating your chlorine. Follow the SLAM Process first and then you can look more into the other issues.

That's the truth right there. A high CH could result in scale not rust. Are you on a well in your area? Sounds like you might have an iron issue. Try a Vitamin C tablet on one of those stains. Rub it right on there and see if it lifts.

As noted above, if you have algae, it's SLAM time. SLAM first and treat for metals last if that's applicable.

Where would I get a Vitamin C tablet? Is this specific to pools or are you talking about your run of the mill Vit. C supplement I can get at CVS?

Yep, the CVS/Walmart stuff. Tabs though, not gels or gummies.
