I've tried both Stability and Bio-Spiria and still ended up with dead fish.
Found best way was water treated with Prime, water changes out the backside, a batch of zebra danios and patience...as aggravating as it sounds...and it is.
But, after those three or four weeks of aggravation, everything I've added since has lived happily and show it by mating in the plants, leaving me with way too many fry!
The longer I'm involved in this hobby the more & more I'm convinced that Bio-Type species tanks are the way to go. Plants and fish/inverts live together in nature for a reason. I find the less I try to fight nature the better my tanks look.
