Prazi-Cura Liquid - Safest, Most Effective Parasite Treatment for Koi, and Aquarium Fish! Treats up to 2500 gallons.

Community tank had wasting which I identified as possible parasites. Other meds didn’t make a difference. Treated with this and three days later I could visibly see it was working. Way more cost efficient as well vs the 1 pack per 10 gallon meds of other brands when you’re treating 75+ gallon tanks.

I was not aware of this product until recently. I have some Koi that were not eating and swimming erractically. I tried some other meds but after 2 weeks, they were still the same. I decided to give this a try even though it is very expensive at $49 for 16 oz bottle. Mixed recommended amount with some water and distributed it in the tank. Also removed carbon in the filter system leaving only the pads. Your water will get cloudy without the carbon but that is what you have to do. My Koi fish started eating after third day of treatment and they also starting swimming a little more normal. After 7 days, I did a partial water change and gave the tank a second treatment. It has been 3 weeks and the fish seem to be back to normal. It should be noted that I also added aquqrium salt to the water so that may have had a beneficial effect. In any case, I would say this med did its job. Use it if you have expensive fish.

Mixes surprisingly well for a typically hydrophobic medicine. This is a great deal on Praziquantel if you're looking for it for your large aquarium, as the bulk pricing saves you a ton of money.

Very easy to use. Took care of those darn Flukes in our pond.

The skin parasites cleared right up. My koi seem as lively as ever. I plan to treat my pond with this stuff 4 times per year.
