somewhat misleading info from the LFS
high nitrates don't cause HITH, but it is suspected that they weaken the fish and make them susceptible to HITH
yes, they can live with HITH, but that doesn't mean it is ok for them to get it; i.e., it is still a bad thing (and certainly unattractive)
no one should argue that plants will "get rid of your nitrate problem", but they are a tool to be used in controlling your nitrate problem . . .
and of course, he took the opportunity to sell you "meds" . . . well, good for him
