Calcium Chloride in July?!

[TexEdmond]

I was considering raising my CH numbers slightly, but it's very difficult to find anyplace that has high quality calcium chloride in stock. I see many of the "CaCl ice melt" products are shockingly low in CaCl as a percentage, once I dug into the MSDS sheets. Some of them simply withhold the concentration as "trade secret."

I did find one that looks trustworthy and had to share the hilarious nature of automated shipping calculators:

"You want it... one day sooner maybe? Okay!"

A CH of 325 is well within range. Why add any?

Use Cal Hypo to chlorinate for awhile.

This was back before you pointed out that the Cal-Hypo I was adding was the likely cause of my skyrocketing pH and calcium dusting issue. To fix that I was thinking about lowering alkalinity down to 50-60 and bringing CH up to 400-425 so I could stay in the "slightly negative" CSI for the salt cell. Not gonna do it anymore, because after I quit putting Cal-Hypo in the pool, the pH has magically stayed at 7.5 for 2 days straight with no acid. Now, that's also because I've got the puck soaker and a floater bringing my CYA levels up slowly. Headed to the Home Depot for PVC and 16 bags of salt now. I swapped out the ozonator for the SCG power center yesterday.

OK -- too many different threads. This is why it is best to have one thread for inter-related items.

I still would not add calcium. I suspect your fill water has calcium, and you occasionally have to use fill water.

Totally agreed. I'm not gonna add calcium. I was overcomplicating things; par for the course.

Fill water hardness is 175ppm.
