Shanny,
You could check with others. However, the Rep Cal is supposed to be a good supplement.
I hope so, as it is the only one I have ever used. I remember reading an article , online, regarding using vits and Ca on separate days.
I'll try to find it. I think I will start to keep better track of these things.
The article was specifically about housing a few frogs (or more )in one enclosure, increasing the chances of them getting what they need.
