Where to get Formalin?

[pelle31]

I used formaldehyde when I had an airborne disease on my Discus. The last poster is correct,if there is white on the bottom do not use,it is quite deadly. When using as a dip
it worked quite well although the smell when dipping the fish was disgusting. Keep a close eye on the fish as well and use a net for the dip. Good luck and I hope it works out for you.

I believe I bought mine from Safeway Pharmacy.
