About a month ago I had an angel fish introduced into my tank with Brooklynella. That fish shortly passed but then both my clownfish contracted the parasite. I’ve used this treatment for about 2 1/2 weeks to help my clownfish and not kill starfish, snails, etc. My female clownfish was on the brink of death and now she’s completely back to healthy and happy! I’m so happy with this product. It’s a great alternative for copper infused medications if you need a reef safe option.

My betta fish got the parasite velvet, and I thought he was a goner. I started giving him this treatment as soon as I realized there was an issue (he had the gold dust appearance from the parasite). Soon he got a lot worse and developed bad fin rot. This medicine helped him pull through though!!! Couldn't be happier. It worked as a great alternative to the copper treatment which is harsh and can't be used with plants or invertebrates (I have a planted tank).

I purchased this ich treatment after my tank was infected by introducing your fish. I treated my 5 gallon tank with the recommended dosage and it paralyzed my corydoras! I did a prompt 50% water change and fortunately they came out of their stunned state. This was medication that your store associate picked out for me. I know corydoras are sensitive to treatments to begin with, but I'm unhappy with my Petco experience. As for the effectivity of the medication, I'm unsure at this point.

I don’t think this work, I put it in to my fish tank , my fishes were acting weird and all die, also has a very strong smell i dint like.

It’s just bad get API he’s not as effective as a PI is one of the worst

Do I bought this 2 days ago wish I would of taken pictures of my fine line tang he was covered from head to tailfin by white spots. I thought immediately it could be velvet well I'm not a lucky one to have a current qt tank setup so I came across this. Hesitant to buy because of horror stories of this being added and all fish go belly up. Well today marked day 2 of adding a dose. And just got home from work and the tang is back to normal not one single spec on him. Also had a clownfish starting to get it, gone. And a black blenny he started to get it on his head. It's all gone and it's only day 2. Understandable the parasite is still in my tank but this has taken it off my fish. If you continue treatment for a certain amount of time I'm hoping it's like you have a fish less tank and can rid the parasite. Copper is not an option because I want to eventually make a reef and also I have shrimp snails hermits etc.

If I could give this 0 stars I would. Dosed it correctly with daily 1/3 water changes after finding out my tank had ich. After the third day I saw the ich got extremely bad. 4th day, my entire tank is dead. Would’ve had way better luck if I didn’t use anything at all lol. This is the only treatment i had available at the time. DO NOT BUY THIS

Purchased this through the recommendation of Jason who works in the Middletown NY store. This works great. Put this when you spot something wrong with your fish or when adding new ones.
