Re: [AGA Member] disease issues in a display tank

Did you try MelaFix -
http://www.pondrx.com/shop/details.php?productId=39&catId=5
Designed mostly for ponds but I think they have developed it as well for
other tropical fish.
I think the new ones does not harm your Filter Bacteria but donno as for the
plants.
What about major water changes ???
