Need 2nd Opinion on % vs Volume vs $ calculation/assumptuion

<sigh> a second update...
I wanted to work the angle on giroup01's suggestion of using CalHypo...
I have been searching around for info on whether CalHypo will increase my Calcium levels (which it will...so forget it)...and becuase I used "calcium hypochloride" in the search string...I ended up bouncing across a couple more "cost vs chlorine types" threads...and one driven by ChemGeek even. I'm sorry I missed them when I started this thread. :(
I don't want to flog a dead horse, and although I just skimmed the other posts (will get back to them...too late tonight) I suspect they are well and good for the cost vs chlorine I was trying to originally figure out.

Also...(not having read/searched other posts fully)...I also suspect Carl's post about determining PPM of the 'stuff' you have is the better place to continue the 'discussion' of the methodology and interpreting the results.

I don't know what other meat is left in this thread, after considering those other ones...I'm too tired now to suss it out.

Mod: if you feel this thread is now pointless and/or should be pmoved/closed/deleted...I trust your judgement. It's always best (and very hard) to keep like info (and usefull info) together...

How are you coming up with X% of Yliters = $Z/ppm?

Is there some constant to describe how much ppmFC there is per %SodHyp?

0.9525
10.8% sodium hypo * 0.9525 = 10.3% available chlorine content.

Keep in mind that the pool will be opened about 4 months a year, and come October you'll drain it 2/3, whatever's left will be diluted by rain and melted snow, then you'll top it off in April with tap water.

So the increase in CH, whatever it is, is irrelevant.

Well, not quite...

I have a DE filter so I don't dump & fill on a regular basis. Rainwater duming is all I'll be doing.

I plan to close my pool way late and open it way early. This is my first run but I'm thinking April to November...we'll see how reality goes...

I also only plan to drain below my returns, leaving them open to allow overflow to drain out the pool. Opening 'refill' will only be about 6 inches.

I have no idea on the 'rate of rise' my calcium would have, if I used CalHypo...but there won't be the dilution you're suggesting.
