I can’t rate this high enough!
This has saved fish in my saltwater tank from dying, and in my freshwater shrimp tank. In my saltwater tank, I thought I had a fungal infection, but turns out that wasn’t right. Within a week of dosing this, the pop eye and cloudy eye on my fish was totally clear. In my freshwater, shrimp tank, cherry shrimp and Chili Raspbora, I started to recognize that I wasn’t seeing baby shrimp anymore. Shortly thereafter, I recognized all the flat worms on the glass and in the sand. Literally within 24 hours, there is not a single flat worm, cruising my glass at feeding time and I can see them dead in the sand. I will still do the second dose in three days, to get the rest of them. What an amazing product

good product for parasites - thought delivery was slowed down some
It is what it said it was - there isn't much information on the bottle to explain how to use it - had to look it up online. At one point amazon said it would be here in 2 days - it arrived after 9pm on the third day. It started out usps then switched to ups and that slowed it down. It is in a small bottle and I think without switching delivery service it would have arrived in the morning. I'm not sure how to fix any of this

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.

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.

Very Effective
This works fast and doesn't hurt the fish. It can kill the snails so we put them in a container of water for 24 hours. We make sure to unplug the filtration system so the medicine isn't filtered out. It is so easy to use and the color fades as it works. The price is well worth the results.

Effective and Quick!
Unfortunately had the case of some of my fish getting worms and none of the typical salts or other products were working. This got rid of them so effectively I’m impressed! Definitely a good product to have in your arsenal for lasting fish health when hard to kill parasites are at play

Okay
Works great for fish but beware of bacteria bloom after! Only use in quarantine… please saltwater friend to another

Works Great
I know it’s not what is meant for, but I used this to treat a new tank for planaria and this combined with no food actually eliminated them all together. I will say that it leaves a slimy film around the edge of the tank but I’ll take that over the worms any day.

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