Cleaning pre-owned tank

[mrsjoannh13]

Hello, everyone!   So I just got a 20 gallon UNS tank from my LFS.   It was a display tank in their store previously.  It's been drained for maybe 2 weeks now.  My question is....   How would you disinfect the tank?   To my (and the LFS's) knowledge there were no diseases in the tank prior to them emptying it for me.   Would 2 weeks be enough time dry to kill off any nasties?  Or should I wipe it down with bleach just to be on the safe side?

Thanks!

2 weeks should kill off any nasty's.  id give it a good wipe out with warm water, and white vinegar. i personally dont use bleach on anything in, or near my aquariums.

I agree, bleach (chlorine) is too nasty.

Hydrogen peroxide is an option, still probably overkill but safe - potential residue breaks down gracefully in opposite to the above.

Salt! Common salt is cheap, harmless in residue concentrations and lethal to many (almost all, I'd say) organisms in higher concentrations.

I'd probably just clean and let dry though. Maybe sponge with brine.

I would just rinse it out with some hot water and scrub the sides with a brush. It being dry for 2 weeks should kill anything you don’t want in your aquarium.

put it in the sun then clean it with vinegar and water and let it dry for a week

I always use isopropanol to clean my tanks as it evaporates away and is one of the main ingredients in a lot of antiseptics and disinfectants.
