Goldfish to tropical, cycle advice?
 
I have a 55g fancy goldfish tank, in the past month i've lost 2 out of 4 fish to dropsy and pop-eye (probably bacterial related) I'm giving the goldies away and changing to tropical. Should I sanitize the tank to rid the bad bacteria and lose my cycle or should i just remove the goldies wait and a couple of weeks fishless for bad bacteria to go away (if thats how it works) and keep my cycle. I'd rather not re-cycle but I want a clean disease free environment for the new tropical fish. Thanks.

hmm not sure exactly, this might sound wieird but ive never had a disease or harmful bacteria b4! but if i had problems like that nad i was gonna start over the tank anyway then id say sanatize the tank. IM by far not a professional at fish diseases however

hopefully Byron or someone else who knows will answer, but I'm a worry wart anyway and if it were me, I'd want to clean it all out and start again, rather than risk anything.. considering also that goldfish are such heavy waste producers and all...

But take what I say with a grain of salt.. Like I said, I really have nothing to base it on.. just my own paranoia =)

Most of the dropsy cases by goldfish are water quality related. What are the water parameters currently? What is the history of your fish? Were they all treated with praziquantel before? That would determine if your fish's cases point to bacterial infections (secondary to parasites-common among goldfish) or water quality.

I'm at work so I don't have numbers right now but I've never used praziquantel(never heard of it) before or anything other than melaflex. Do 50% water changes every 2 weeks. Use 2 ac70's for filtration. The two that died(orandas) were over a year old, and healthy up to that point. One had pop-eye then died of dropsy a few days later the other just puffed up one day and died. I've also had finrot in the past(the white tearing kind) but that cleared up months ago.

nitrate: 30ppm / nitrite: less than .5ppm

How about the ammonia and pH? Your nitrite being that high can contribute to the issue. Fancy goldfish are very prone to poor water quality. All these issues stem from water quality issues to me.

I don't currently have an ammonia testing kit, I guess I thought the nitrate/nitrite was enough or could be used in place of a NH3 test since the ammonia is converted over. Bad assumption on my part. My nitrite is always that high so I didn't think anything about it. I've never tested pH since I've had my tank.

Might want to work on the nitrite before investing in tropical fish... Plants may help.
