If you have a Koi Pond you need to keep this on hand before it is needed.
Why did you pick this product vs others?:The pump went out in my Koi Pond and it took three days to get parts to repair the pump. Â Unknown to me, a Parasite developed in my pond and killed out about $800 of my largest Koi Fish. Â I did an extensive search for something that would kill out the Parasite it took about two day to get this treatment in, and I was able to repair my pond pump while waiting. Â This product quickly killed out the Parasite but unfortunately my Koi were already dead.The container is not as big as I thought but I plan to purchase more to keep on hand should this happen again. Â it’s a good and effective product.Functionality:It works!Fish health:All of my larger Koi are dead but what is left seem to be very good.Value for money:At first I thought it was pretty pricey, but was a site less expensive than the loss of my Koi FishSafety:It is recommended to wear gloves when using but there was no problem safety-wise.Quality:It works!!!

expensive but worked well for me
I used the AquaCura Prazi-Med Fish Treatment, 50 grams, to deal with parasites in my koi pond, and it worked well. The active ingredient is praziquantel, which is known for targeting both internal and external parasites like skin flukes, gill flukes, and tapeworms. Itâs safe for the fish and doesnât harm the biofilter, which was important to me.I followed the dosage instructions carefullyâone gram per 100 gallons of waterâand spaced out two treatments as recommended. I dissolved the powder and added it near the filter outlet to help it circulate. I kept the pumps and filters running but turned off the UV sterilizer and removed any carbon from the system during treatment.The fish didnât show any signs of stress during the process, and I noticed a clear improvement within a few days. Less flashing, more active behavior, and normal feeding resumed, which made it clear the parasites were under control.Just be careful with the measurements, since accuracy really matters here. Too much or too little can either stress the fish or leave the parasites behind. Overall, it was easy to use and effective, and Iâd definitely use it again if needed.It is quite expensive, unfortunately.

Good treatment for parasites and flukes, Prazi-Med Fish Treatment, 50 Grams
This is a value oriented treatment for flukes and other parasitic conditions in your pond, tank or aquariums. I believe the value is excellent when compared to dead livestock. Keep in mind it’s NOT for food fish or human consumption. It has very little effect on plants and scaleless fish, but always do a test. Snails and crustaceans would be the most vulnerable by Prazi, so definitely do a test. You will most likely need a second application to kill hatching eggs, so be prepared to do it prior to the effects wearing off of the first dose. Remove any activated charcoal or carbon media prior to use. You may also need a 50% water change between dosing. Prazi-Med name is the exact same thing as Prazi-Cura, so treat the same way.Aquariest always treat chemicals with common sense, with the environment in mind. Please don’t treat where rain or run-off is expected while treating. This is one of the best, if not the best treatment available for parasitic conditions. Dose at 1 gram per 100 gallons, internal or external parasites. Please go to the manufacturer’s’ website for more info about the product and it’s correct uses and precautions.

A lot of good product especially for the price
I havenât had to use it yet, however the amount of product for the price is a great deal. While it doesnât have any dosing instructions, you can easily find the appropriate dose online for your amount of water. This amount treats about 5,000 gallons. It also comes inside of a sealed bag inside of the container so when you open it you donât have to worry about the powder dust flying out. The container is also dark which is nice to keep the shelf life of the product longer.

This worked on our parasite issue.
Well, so far so good. We had quite the issue with visible parasite in our tank that were killing our fish. My guess is they came in the Japanese snail we added a couple months ago. The tank has been treated and all the fish are happy now.

No instructions provided
This is just a bag of powder in a jar, with zero instructions on how to use it. No dosage information for how much you need per the amount of water in your pond, nothing telling you if you prefer mix or add directly in etc. Not very useful if you don’t know how to use it.

Good, general aquarium fish medication
This is an effective general cure-all for your aquarium fish. Does not come with any dosage information, but a Google search quickly solves that problem.
