Hikari Usa AHK73254 Prazipro for Aquarium, 4-Ounce, 2-Pack

I noticed my 10” Giant Thai Oranda Goldfish was bottom sitting and she passed some white stool. I bought this and dosed the entire 175-gallon tank (7 goldfish total) at 5 p.m. By 9:30 p.m., two of the fish had already passed adult tapeworms. I’m amazed it worked this quickly and how surprisingly big the worms were.

This is by far the best medication I have used to rid fish of parasites! Very fast acting!!

Works really well! I had a discus with white poo and treated just to be safe.

This is a must have for getting new fish ready for your aquarium.

This is a great product. I'm docking it one star because the print used for the directions is ridiculously small. I know it's a small bottle but come on you need a microscope to read them. Here they are for those you like me that can't read them from the Hikari website.Directions For UseFor treatment of praziquantel-susceptible disease conditions in pond, freshwater and marine aquariums and ornamental pond fishes. AS A BATH: Start treatment with as large a water change as practical or start with new water. Any water used should first be conditioned with ULTIMATE or a combination of Liquid Buffered ClorAm-X and Stress-X to remove ammonia, chlorine and chloramines. Do not stop filtration, but remove activated carbon and stop foam-fractionation (protein skimming) and UV sterilization. SHAKE VIGOROUSLY before use. Measure Aquarium Solutions Liquid PraziPro at the rate of one (1) teaspoon per 20 gallons of water to be treated. (one (1) fl. oz. per 120 gallons) Measure Pond Solutions Liquid PraziPro at the rate of one (1) teaspoon per 32 gallons of water to be treated. (one (1) fl. oz. per 200 gallons) This produces a concentration of 2.5 mg/L. Distribute the proper amount around the edge of the aquarium or pond or directly in to the filter box to achieve the best overall distribution. A single treatment lasting 5-7 days is normally sufficient. Repeat as necessary, but no more than once every 3 to 5 days. May be used as a preventative, at the standard dosage, when disease is likely. Do not use with other drugs or disease treatments. May cause temporary foaming.

Best parasite med for saltwater reef tank.

Loved it. Treated all my tanks and lost no fish.

Just did not work; I am sure he has a bacterial infection too...my tank leaked I had to half drain it as I had no back up tank, the filter then would not work he was in unfiltered water for 3 days so likely bac infection and this did nothing
