    Took care of Cyanobacteria

    By SealbeachComber on May 21, 2021

    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.

    Did not work at all

    By jrock on Feb 10, 2021

    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

    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.

    Really Works

    By on

    I was shopping in a general store one day when I noticed the Goldfish they were selling were very sick. One fish had fin rot so bad it's fin had been eaten down to the flesh. I asked if I could have it for free cuz I said I would have to pay for the treatment. So they gave the fish to me. 8 days of erythromycin, the fish got better. 5 months later the fish (Twitch) is thriving and it's fin is growing back. This medication is my go-to! Please take note of the before and after pictures of the goldfish.

    Cured my fish !

    By on

    I purchased this by accident . It was the wrong antibiotic , so I thought . When I opened the box and realized it was not the one I was looking for I contacted Chewy and they offered me a credit right away . All they asked was that I donate this to the nearest shelter . They were super helpful . And very considerate regarding the health of my fish . They tried to find the meds I was looking to buy unfortunately it was no longer available in their store or online at all. The next day I decided to give this a try since my fish was near death anyway . He was pale , not eating and his spine looked like he was bent in half . He kept going to the top gasping for air , then sink right to the bottom I purchased this by accident . It was the wrong antibiotic , so I thought .

He kept going to the top gasping for air , then sink right to the bottom . This was going on for a week I knew I needed to act quick or he was going to die . After removing the carbon and following the directions to a T he came back to life , it was a miracle . His color came back . He started eating again and I notice he didn’t look ‘bent’ anymore . It was a Miracle . Not sure what was going on with him . Maybe he hAd caught some bacterial infection from the water change or something cause this happened to him 3 weeks after I changed his water . He’s a happy fish now . He greets me every morning for feeding -time like his usual self . If it wasn’t for Chewy convincing me it might work I may have never tried it . So thanks Chewy . You saved my fish … more

    Reef tank and brown jelly disease

    By on

    Works great in my saltwater tank when brown jelly disease pops up on my lps. Good to have on hand if your corals need more than a water change or iodine dip.

    Saved my pond gold fish.

    By on

    Worked great to save a larger Older pond goldfish. I isolated it to a 10 gal tank outside in shady area With an aerator dropped in and one floating plant. Covered with netting and did 25 % water change a day with medication stirred up for 4 doses/days. Observed and relocated fish back to pond and it acted Like a juvenile again. It had injured itself .scratched scales caught in skimmer brush and picked up bacteria infection. This product worked amazing. I will now keep some in stock at all times.
