I have 3" pucks where Trichloro -s-triazinntrione is the active ingredient 94.05%
Also been using Sodium Dichloro-s-triazinetrione-Dihydrate is the active ingredient 99%
The latter is the granular chlorine I have been using. I believe the 3" pucks have been increasing the pools CYA.
Is the granular chlorine also? I have been using the pucks for about a year. Just a month as to the chlorine.
CYA has increased to 125 from 100. Just ordered a TF-100 test kit to be positive of the readings. The CYA
readings came from the pool store.
