We have been using the Kent Marine Part A&B two part system in our 10 gallon nano for a few months now. It is not the nano part a & b, I do know what the difference is between the two but our corals have been growing nicely since we started adding it.
Based on the fact that it is half as potent and more than twice as expensive as the normal Kent two part, I think it is probably their equivalernt of B-ionic bicarbonate, or my DIY Recipe #2, which does not have a pH raising effect.
