So my fish has had fin rot for around a month now. Repeated dosing with Melafix and water changes didn't really help. My water parameters were really good. No nitrites and less than 5 nitrates. So I couldn't figure out the problem....
I noticed some algae growing on my driftwood which is a very large piece 3' X 4'. It's been floating because it's basically uncured. So I figured I'll take out the DW and do a complete 100% water change. My tank is 680g so it's a big job. When I pulled out the driftwood it smelled like raw sewage.
Obviously it was decaying and still had bacteria in it. Needless to say the piece won't be going back into the tank. I plan to power wash it and blow off most of the soft bark then let it sit outside for a good year. Then I'll try it again.
I got the piece from the driftwood store and I suspect it's basically a dug up piece and not really cured. So moral of the story is be careful of the DW you put into your tank.
