Re: Cal+, does it do it all?
Calcium Plus, as good as it is, has to be designed for a specific set of circumstances. Its balance of nutrients is static, not dynamic. That means that it is treating all frogs the same regardless of their age, whether they are breeding, how often they are fed and what they are eating, etc. Repashy has done a great job with this balance for most instances, but it may not capture every situation. Some folks choose to augment with other things to alter the balance to reflect specific situations. I have heard of people doing this regularly with Vitamin A in breeding situations but some folks will also add things like Superpig or Super Vite or other things. For the majority of situations, however, Calcium Plus is great.
SM, I am curious about your comment about Vit A being more necessary for the offspring than the adults. My experience has been that I need to start monkeying with the balance of things when I am getting repeated instances of infertile clutches from the parents (not that this is always the problem - it's just where I start trying to solve it). I had never heard reference to needing to make up for a deficiency in the offspring. I suppose it makes sense that if the parents are barely scraping by on a given vitamin, that situation would pass on to the offspring, too.
