If you donât have it get it!
I feel this product is a must have. Iâve been noticing my koi on the bottom of the pond not coming up for food and barely seeing them swim. Iâve checked the water quality, that kept coming back fine. I did a partial water change. And it was still the same. I did so much research. I finally concluded that they may have parasites. I purchased this product due to the reviews, and the fact that itâs doesnât harm plants. Literally, the very first day I used the correct dosage, I came out hours later and seen the koi starting to swim. After the 7th day, i did a second dose. And my babies look happy, they are eating and swimming. So I now keep a bottle of this exact brand, for a preventative treatment. I had to leave a review because this WORKS. Believe me!!

Worth a try it worked for me.
This is my review and my experience with this product. I tried lots of things for my Discus and you can only tell what your fish may have but if your wrong then you have to keep searching. My fish was face down and I tried everything that had to do with face down Discus and had no luck. I would do changes of water 25% 50% and 75% and still no progress. When I saw this product I figure what can I lose my fish might not last long. So I brought this product followed the directions and in about a week my Discus was facing straight and another week he was back to eating and swimming back with the rest of the pack till this day. Sometimes we try what is told to us by searching the Internet. I would say from experience if you read whats on the internet and sometimes it works but if it doesn’t work try another product because it could be some other disease.

Seems reef safe
Iâve now dosed PraziPro twice, in my small reef tank, a week apart. I had two clowns, gramma, watchman goby, and neon goby. The clowns and gramma had been rubbing themselves on sand for a few weeks; the neon look filmy, with spots. I diagnosed flukes, though I wasnât certain; a freshwater dip seemed risky and I could never catch all these fish in my tank anyway.So I dosed 3ml one evening. Next morning, goby was dead. Everything else (zoas, hermits, shrimp, snails) was fine. So strangely, the worse effected fish, the neon, (which are prone to infection according to online forums) died after treatment. It may be that the flukes react to the meds by hurting the fish more as they die (as the Wikipedia article about praziquantel suggests).This morning I dosed again because clowns and gramma have still been itching. Within a few minutes, the gramma was thrashing and scratching like never before. Seems to be another reaction of the flukes to the med. So now weâll see…The clowns, which are apparently somewhat resistant to flukes, seem fine, though theyâve continued to scratch on the sand.The best news, so far, is that the other animals seem fine, though with another dose in the tank, weâll see. The bottle says âextremely safeâ and that you can dose every 5 days or so. But does it break down or build up in the tank?

Seems to work
I’ve been using Prazipro on and off , about a year now. I have a mated pair of black and white clownfish that seem to have a recurring case of flukes. Usually, I just dose once or twice and they seem to go away. But they always return, even though I don’t dare add anything new to their tank. This time, I did some googling, and discovered that you need to keep treating for at least 3 weeks. I finished that a couple weeks ago and so far so good.

Great preventative medication
I use this as a preventative with each fish I purchase in a quarantine tank.I dose the recommended dosage a day after my fish arrive. After 1 week, following a 25% water change I dose again. If all if well with the fish after 3 to 4 weeks, they are introduced into my display tank.Safe and easy to use. Don’t use with any other medication except copper if needed. Don’t use protein skimmer, carbon or uv with the product as it makes it ineffective.

Product came in oily around the bottle and the expiry blurred because of it. I’m not sure if i want to use it for my fish as i’m worried it may cause harm.
