    Roger, it forms several types of polymers as well as a trimer. These do revert to formaldehyde on proper treatment.

    I think formalin solution is usually stabilized with methanol, which increases its shelf life. At least mine is. Is it available without methanol stabilization? If it is, make sure you get the stabilized version, because the methanol doesn't cause any problems.

    So I can use a 37% dilution of 10% formalin?

    Fishy formalin

    I just got a pint of formalin from petsolutions.com (via Amazon) for not a lot of money. No detailed information as to what else (if anything) might be in the bottle, but it does say the active ingredient is "37% formaldehyde." It's a clear liquid and smells like formaldehyde. As a long-time aquarist I know that formalin has been used for many years to treat parasitic infestations. I'll see how good a stabilizer it makes. A pint should last me a while...

    formalin source

    Took me a while to find a source for formalin. Searching through ebay proved fruitless !!

    I'm not affiliated with this guy just found his prices reasonable.
