Question about CYA reagent R-0013

[Watermom]

There really is no way to know how much chlorine you'll lose. If your solution got somewhat cloudy, I would say that you have some CYA in there as opposed to none. If you are showing less than 30 and you haven't added any within the last week, maybe add just a little. Maybe enough to add 10ppm. So, even if you are at 30, that would just take you to 40 which would be a good level. A week after adding it, test again and see where you are then. At that point, you can decide if you need to tweak it any.

I'll know exactly later this evening. FAS-DPD kit came this morning. I'm gonna go with 30 too. First thing I learned from Ben and you guys is know your CYA. I figure I'll be able to use up about 20 oz's of old Dichlor to bump it up ten. It takes 1.8 ozs of Dichlor to raise chlorine in my pool 1 ppm. Am I right in assuming that Dichlor has a 10 to 9 ratio of chlorine to cya?

Yes, you've got it...glad your pool is looking good, and have fun with your kit!

This is more funner than my first chemistry kit. That one only came with 4 bottles. I think they were fire, water, earth and wind.

FWIW, the HTH kit does use Taylor reagents and is rebranded by HTH. (The HTH test strips are rebranded Taylor ones also, btw).
