Yeah. Having calcium that high with an SWCG is likely to lead to a fair amount of cleaning. Let me ask PoolSean and Chem_Geek about this. I think high calcium alone affects scaling, so lowering the pH and alkalinity won't help, but I need to ask.

One other question: have you tested the tap water, to make sure it's not high in calcium? I don't think that's usually a problem in NJ or Florida, but we'd better rule it out.

Checking on a partial drain and refill is a good idea, But, to see how much to drain, we need both pool CYA & CAL levels, and the CAL levels in her fill water. Do a 50:50 dilution of pool water to tap water, when you retest CYA, and then multiply the result by 2.

Aylad, there is another way to lower calcium . . . but it's sort of a pain. You have to take the pH up over 10, and collect the calcium carbonate that forms on the filter. It's not expensive, now that washing soda is widely available for cheap, but it's messy, and you end up with high alkalinity, which you then have to strip.

Don, let me know if you are interested.

[ Yes, this thread has been edited. Watermom emailed me to let me know I was going crazy -- she said it much more nicely than that -- and mixing up threads. Hopefully, I have it straightened out, now. I've also emailed PoolSean and Chem_Geek about your calcium levels.]

Ummm Ben, I haven't posted in this thread 'til now.....

Aylad, Watermom, whoever . . .

I already acknowledged that I went insane yesterday! (And, it's barely April!)
