I came across HTH Super Shock at Costco. They’re granules but cal hypo and don’t contain CYA. Are those safe to use or does anyone have any experience with it?
It's a perfectly fine run-of-the-mill cal-hypo, but didn't you just drain your pool due to calcium buildup?

To add to JD's comment, make sure you are aware of your current levels. If your CH is high, you probably don't want to use Cal-hypo. You probably get your water from the Edwards Aquifer, so you know how hard your local water is already. Also, using cal-hypo means knowing what your CYA (stabilizer) level is so you are balancing the FC to the CYA as noted on the FC/CYA Levels.
So technically yes, you can use it, but not if your CH is already elevated. If it is, stick to liquid chlorine. Hope that helps.

Yes I did. I have been using liquid chlorine since then. I wasn’t planning on using it and wanted to know if it’s any good because I came across it yesterday. Thank you!
