R-0600 orthotolidine replacement source?

[Pv2]

anybody have an inexpensive source to renew reagents from the TFT-100? My pH rarely changes so I don't test it very often, FC gets tested daily or more often. Found it from the "factory" pretty cheap but shipping was quite a bit more that several refills.

shelf life? maybe I should just buy a large container?

In fairness, if that's all you need, it can usually be found locally at a pool store and should be reasonably fresh

thanks, ordered. I'm pretty far from town and just like to get stuff in the mail
