test kit refills. i looked for it, did a search and didn't find it. I start a zoom meeting in 12 min and I wasted a lot of time trying to find it. We cannot find the DPD powder anywhere here locally - we ran out. the husband used the last of it and didn't bother to tell me and we are in the middle of a slam. I am mad beyond words - esp when he cam home with two packages of algacide stuff.
