good dosage in general cure by API along with prazi in a smaller dosage.. Metro straight costs alot more for some reason even if amount oer oacket is same.. JL has had it in past but call around and see. I know April has carried it also.
Check with April as I've seen it at her shop before. I've bought some from Ken's Fish online before but it sounds like you need it asap. You can get a huge amount online for cheap. There's no reason why its so much money except for companies like Seachem trying to market it as an expensive drug and then sell it in tiny quantities. Very effective on bloat, especially the straight pharmaceutical metro powder.
