    Follow the directions. This medicine has been around for a long time and works. It saved me hundreds of dollars worth of fish from an outbreak of fungus mouth which can become something worse if left unchecked. Thanks Chewy for shipping so fast, it worked well and I have a healthy aquarium once again Follow the directions. This medicine has been around for a long time and works.

    Did not work at all

    It was a shame this was a lot of money for a dud. You would think that a company in business as long as they are would make a product that works

    In lieu of getting into overbooked vet, used this for my dog's ear infection in combination with ear powder and wipes and hes back to 100%.

    Super helpful for fin rot!

    By on

    My Nemo's tail was ragged; this and API Stress Coat+ and water changes helped so much! Follow the directions and fin rot will be gone in no time. It's snail safe, too!

    Great product for fin rot

    By on

    Bettas are prone to fin rot. I’ve used several products but this seems to work best.

    Took care of Cyanobacteria

    By on

    Couldn't find this locally. Shipping was a little slow. But it worked. I followed the instructions to the letter (had to read them three times because the wording is awkward) and the nasty emerald green stuff is gone. Before I started, and with each water change, I used a bare syphon tubing end to vacuum up as much as the stuff as I could.

    Treatment for Blue-green algae

    By on

    We purchased this product to remove blue-green algae from our aquarium. One treatment and it is gone. We did a follow-up treatment just in case but I really think 1 did the trick. I can finally turn my lights on the tank again.

    Not sure if it works

    By on

    I used it as directed. He seemed to do better. Then fungus came back. Tried to treat again. This time he spazed out. It might have been too soon. I did a water change, put a filter in, and he seems comfortable. This stuff it hit or miss like all meds for animals and humans. My fish might just be too sick.
