Here I am again, always trying to find the elusive Dichlor product in order to add CYA to the pool. My CYA current level should be at 23 (I still need to test) based on dichlor added about a week ago, and the chlorine is holding pretty good through the day, but wanted to have some more on-hand. I've searched the forums and I know that Sodium dichloro-s-triazinetirone and Sodium dichloroisocyanurate are the same thing. My last purchase was an AquaChem product that is no longer available. However the product I found today is 99% Sodium dichloroisocyanurate dihydrate.
This is okay? Thanks once again.
