I've seen a lot of postings about concerns about too high CYA levels when using chlorine products. I seem to have the opposite problem.
I have a SWG and often times my CYA always tends to drift downwards thru the course of the year (more so in summer). So I find I need to add more conditioner. But I find conditioner to be expensive. Also, I also like to shock my pool with dichlor, as it raises my chlorine level quickly, dissolves fast, and also bumps my CYA. So how can I calculate how high my CYA level will rise with dichlor? I don't really see any mention of how to calculate this anywhere.
