Ok, so I've read on here that the pond versions of these can be used in the aquarium. The pond pima contains like 2% of the active ingredient (pima-blah-blah-whatever it is), while the aquarium only contains 1%. So would I just cut the pond dose in half to equal that of the aquarium version, or is the pond just safe to add as is? Same with the melafix, except it's 1% in aquarium version, and like 5% in pond. Any help would be greatly appreciated.
