Worked as expected
Pretty sure it cleared up the flukes in my fish tank! The container was smaller than expected, but it only required a small dose so its easy to use and I have a big tank so good value for money.

Will update with results
The bottle comes sealed, which is awesome. The bottle is very small, which is fine, just don’t be surprised. Followed directions and casted my first dose right away. I’m trying to get rid of these planarian before they harm my snails. So I will update with the results.

Reliable Product. 1 oz size will dose 20 gallons 2 times.
Good product, works as needed. Follow instructions- you'll probably have to look them up online to READ them, since the label is pretty small print. Product size: 1 oz is sufficient to dose 20 gallons 2x.

My go to parasite treatment for quarantine
My go to for new fish. I feel this is a very safe medication to give during quarantine and works quickly. I like to dose half the concentration of aquarium salt in my 10 gallon quarantine tank to aid in stress relief and healing and the prazipro (regular dosage for 10 gallons) So far it’s been the best cocktail.

We will see if it helps.
It’s about 5 teaspoons full. I have two tanks that are 55 gallons each. I treated both and almost nothing was left. I’m not sure why the barcode was blocked out. I’m also surprised at how small the bottle was. But I guess that’s my fault for not paying attention to the ounce Size. I have just treated the tank where I have one fish that has an ulcer on his tail. Could be a parasite or something else not sure but I’m treating the tanks anyway.

Super tiny bottle.
Stuff kicked in fast. Added to water after not feeding fish for a couple of days. While it was fresh in water i added flake food it soaks up medication and is injested. Let the fish over eat. A strong dose is insured and a better treatment or attack on the cause of illness.

Expiration date changed?? Medicine partially working
I feel a bit funny about using a product that has one expiration date on the bottle then another very different date pasted over it (on a seller's label). The silly second label was so difficult to get off too! It practically destroyed the "original" label, making it nearly impossible to read the directions. But I had a shrimp disease that this was supposed to fix and didn't want to wait to order a second bottle. This brand is touted to usually take only one single dose for the specific disease. It's still pretty evident it's there, and the medicine is supposed to be effective mostly days 1-3. I will dose again soon on day 8, so I can't say whether this is working or not. I am a little curious if the product is an authentic product in good condition. No shrimp are dead at the moment, at least. Not returnable so buyer beware on Amazon purchases. Update: I'm not sure this had any big effect, and it ended up killing a bunch of shrimp on the second dose that the product recommends. I did the water change it called for, but I would still lose shrimp 1-2 days later, all parameters perfect at time of death. Too bad this product is not returnable and sellers can manipulate the expiration date. The shrimp seller who gave me the disease bought his own bottle and eradicated it with one dose of the product. Amazon buyers beware.

I didn't see any improvement in my sick discus but it extended the discus life in short term.
