Does this product contain either Copper sulfate or Terramycin?

No it does not. It contains water neomycin sulfate, methylene blue, proprietary polymer mixture, buffers, EDTA, malachite green chloride, cyanocobalamin and electolytes. My Betta was ill for weeks, and this bought him back. I now change his 2 gal. tank every week, and add 1/8 tsp of aquarium salt with each total water change. I also have a heater pad and filter in his tank. The temp stays around 80 degrees, and he seems to be thriving again.

will this harm the good bacteria in my filter?

Hi! That is a good question. In all likelihood, it would probably kill all bacterias, good and bad---so, I would remove your filter pad/& "comb" while treating your fish--if possible. I didn't treat my Betta in his tank. I put him in a little isolation cup w/ a lid to treat him daily, along with 100% water changes every couple of days. He was so sick, he wasn't swimming around, anyway. I still can't believe that this stuff got him better. I honestly thought I had lost him!He's doing great to this very day!!!

After just once use my betta has already perked up some :) but the package says to use for at least 3 days. Do I change the water every day first?

You definitely don't want to add more medicine without changing water - that will be an overdose for your delicate little fish. I'd recommend changing as much of the water as you can and completing the three day cycle.

How much of this do you use? i have a 15 gallon tank. do i use the whole container? how often should i dispense it?

I believe it is 8 drops per gallon, you should replace daily for best results. However, since your tank is so large, I suggest putting you infected fish in a smaller tank, perhaps a gallon or a half gallon, and treat them there with the medicine. I hope this helps! I wish you fish best of luck!
