HCA: Hermit Crab Association

I have been using zoo med drinking water conditioner in my tank. I was wondering if its fine to use it or should I get a different kind. And if so what kind or brand should I use??

that's what I've been using since I started last summer and I'm trying to find out the same thing! that and the HBH hermit crab salt that I'm using

For the regular drinking water I use spring water and I use a aquarium decholirinator. For the salt water I use Instant Ocean which can also be found in the fish supply section.
