Prazi is NOT formalin based. Prazi is gentle enough for puppies and kittens.
It will help to rid your fish of any internal parasites as well as the
external ones. As opposed to SupaVerm, Prazi is "approved" for use on ALL
fish, including tropicals and catfish. SupaVerm is actually a sheep dip; the
use of it for koi is in a "grey" zone - and it can ONLY be used on koi.
Other fish will die a very nasty death.

Prazi can be used independently of Proform-C, the combination of which
comprises the so-called Silver Bullet (formalin, malachite green and Prazi
will kill just about ANYthing other than the viruses), but it's a real pain
in the butt to dissolve. After shaking it for (what seemed like) forever, it
STILL hadn't dissolved to any appreciable state. I thought I'd get clever
and put it in the blender: Big Mistake. It will eventually dissolve in the
pond; directions are to dump it by the filter intake.

Winter temps will not bother the med, nor is a water change required after
its use - so it can stay there quite awhile. As the water warms, flukes
become more active and will cause more problems. Your choice: you can kill
'em now or kill 'em later.

KoiZyme is not a med, but a water additive used to reduce the numbers of the
aeromonas/pseudomonas bacteria that will induce ulcers in the areas munched
by flukes. It's very effective, but will not "cure" an ulcer if one is
already present. It's a preventative, not a cure.

Hope this helps.

How soon in spring should you treat your pond with this. It says water
temp don't matter but when would be best to kill the parasites. Has
anyone used this before?
