I use Marc Weiss' Instant Amazon on some of my tanks but I noticed on some of the bottles that I picked up at an auction that they smell. It is an odor that reminds me of something fermenting. The bottles I have used before have never had this aroma btu I have discontinued usage til I am able to determine if it is harmful. I would hate to kill some of my fish due to an alcohol overdose. Any comments ??? Thanks, Gareth Casey ------------------------------------------------------------------------- This is the apistogramma mailing list, apisto@majordomo.pobox.com.
