Used Tank concerns

[Bogertophis]

As an FYI the only disinfectant to kill crypto is ammonia. Now, I doubt that would be an issue with a fish tank, but if you ever get a used enclosure that housed reptiles, you would want to spray it down with ammonia to ensure there's no lingering nasties lurking.

From experience... do it outside. Trust me on this. Then rinse it well multiple times and allow to air dry for a day before bringing it indoors.

And for sure, add ammonia to MY list of disinfectants...instead of bleach, since it's effective on crypto & either one is dreadful to work with & need good ventilation.
I wasn't aware of that, thank you bcr229.
