yes, it's the same medication. crush a pill up in some tank water and sit the coral in it. i've seen reports of people using 10 and 20 times the recommended dose with no ill effects to corals, so overdosing is not the main concern. you just don't want to put an sps colony in it before inspecting it for acro crabs and things you do want in the tank. most crustaceans are toast with an interceptor dip.
