, hypo is the better choice, but again, its gotta be just right or its either not low enough to kill anything or too low where it kills the Ich, but also kills your fish.
Someone correct me if I am wrong, but if this is a FOWLR
and the OP can't do a QT, why not go hypo. I've always understood that it does not totally kill the beneficial bacteria in the system. It will kill inverts and such though.
