Does what it says

I bought this to treat hydra in my shrimp tank after several reviews from this site. It arrived very quickly and I was excited to be able to treat quickly. After a week there's more hydra than ever and I've lost about half of my breeding stock.
Despite several other reviews, I don't consider this shrimp safe and it doesn't treat hydra.
The good news is it eradicated the few detritus and rhabdocoela worms on the first day.

Used In QT Tank.

After reading reviews, I bought this product because my daughter's platies were really skinny and not putting on any weight. (She's 8 and wanted to "rescue" the few remaining platies out of the tank in our local Walmart's closing live fish department. ) After several weeks of feeding them heavily, they were still skinny, so I got the PraziPro to "deworm" our fish tanks. 2 of them got better, second female died through no fault of this product. (My son accidentally caught her while removing a the remaining part of a lettuce leaf he had put in for his pleco (not realizing she was in the net, we left for town and had a crispy platy when we got home a couple hours later. ) Anyway, making a habit of using this product with a couple other products (IckX and Melafix) while QT'ing fish from the local fish store, after having a goldfish that looked clean in the store develop ick (it died), a (replacement) mama platy that got fin nipped and developed fin rot and one set of female guppies (bought day after the store got them and didn't QT) went belly up from shipping stresses... just in case there is any internal parasites going on. Too early to tell if they are "totally cured" yet, as it's been less that 2 weeks since we began using it. I'm happy to update on results later on.


This stuff cleared the parasite worm that protruded from mh betta's body. This stuff is a must in my fish medicine cabinet. Happy with my purchase. Thank you Cory.

Prazi Works... so why buy it here?

I'll tell you why: Prazi-Pro is a relatively non-toxic substance to put in your aquarium that effectively and reliably eliminates flukes and other parasites from your fish tank fast. But that's not the best part. The best part is the amazing education you will get from Cory's Youtube videos, that will let you determine if you even *need* Prazi-Pro! Aquarium Co-Op will take good care of you, so you can take good care of your fish!
