How to sterilize Q tank?

[RobertK]

Hi,

A new fish died in my quarantine tank after two weeks. I think it may have had a bacterial infection, as it had unilateral then bilateral exophthalmos ("pop-eye") and trauma was unlikely in the bare tank. There were no visible abnormalities of the fins, scales or gills, and the fish had been doing well, so I am somewhat mystified. I treated with Maracyn-Two for a few days before the fish succumbed. Should I be worried about the next fish catching something from being placed in the same tank? Is there a procedure for sterilizing the tank? Should I throw away the bio-wheel? I have quarantined many fish over the years but this is the first to have gotten sick and died in the Q-tank.

Thanks,
Robert

bleach.

Ditto (bleach and let air dry).

you can add the bleach with the tank running with salt water in it, most will evaporate if it's an open top in a few days, then use a dechlorinate and test it.

would just hot freshwater suffice?

No, hot water will most definitely not suffice. 20% bleach solution with a contact time of at least 10 minutes, then lots of rinsing, and yes, adding a dechlorinator to the last rinse is a great idea. You'd be surprised at how resilient bacteria are.

Thanks, I will follow your advice. Clean out the tank, soak tank and filter in bleach solution, rinse and rinse and rinse, dechlorinate, hope for better luck next time.
