fill water TA 500!! Richard, Carl, Evan, Al help!!!

Do you also have an acid neutralizer? That is a common setup with well water to have have both the softener and the neutralizer--it's a second smaller tank. And, with well water's pH of less than 7.0, it's VERY likely, because otherwise, over time, the acidity will weaken the pipes in your house.

If so, that answers Chem_Geek's question right there.

Either way, unless you bring in other water, you wil have to do a lot of the T/A reduction. Be VERY careful not to add ANY calcium until T/A is in the proper 80-125 range for nomal pH or your water could go cloudy.

thanks guys!!

richard, as you know, the softener does indeed add salt, and yes i am adding chlorine to the water via injector. the reason the 2nd sample is higher is that the softener has a weak (old) carbon filter inline.
So use the softened water, fix the pH, aerate, fix the pH, aerate and repeat until the TA is 80-90 and then let the pH come up (aerating) until 7.3-7.5 ?
thanks carl, but there is no acid tank used. there are holding tanks that allow the sulfur to precipate out by reaction with the chlorine. the tanks are flushed monthly (from the bottom to let the precip out).
This is a 22-25k salt ig vinyl pool.
you know, on my old pool, the pb used proteam supreme. I read evan's borate experiment, any update? I was thinking of using the borate again. thought's ?
