We "nuked" the aquarium last month after our tiny koi Elmo had a "near-death experience."
We got rid of the infection using a few drops of Rid-All General Aid:
It effectively sanitized the aquarium and also disinfected Elmo -- poured a few drops directly on Elmo's skin err, scales and gills.
Note to self: continuously replace 1/4 aquarium water every week.
