Added more about:

Aqueous solutions of formaldehyde are referred to as formalin. "100%" formalin consists of a saturated solution of formaldehyde (this is about 40% by volume or 37% by mass) in water, with a small amount of stabilizer, usually methanol to limit oxidation and polymerization.

On the seahorse.org there are warnings that one shouldn't use formalin with white residue on the bottom.
The white residue is paraformaldehyde and is considered very toxic and deadly, at least to seahorses.
I don't know if that means the formalin is no good or if one can remove the residue by filtration and use the remaining product.

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.
