Thanks. I know the pucks I had are trichlor. As for mixing pucks with Dichlor, I made that mistake during the first year, leading to draining over half the pool. I stay far away from Dichlor now.
I don't recall the name of the granular chlorine; I purchased, I think, a 100lb container of it, so it's been a long time since I purchased it. But the main thing about it is that it has no cya! :lol: But that also raises another question. What type of cya-free chlorine do folks recommend? I am nearly out of chlorine, too, so I will be buying more of that soon, as well -- probably in the 75lb or so range.
Thanks for the note about looking out for copper re the pucks. I hadn't heard that previously, but it makes sense.
Thanks!
