FAQ

Does this product help treat popeye?

If you catch popeye in its early stages, you can use API E.M. ERYTHROMYCIN for effective treatment. Some signs to look for include protruding or cloudy eyes, either in one eye or both. If you notice any of these symptoms, dose immediately.

Is this ok to use as a preventative if one fish is sick in a tank with other seemingly healthy fish?

API E.M. ERYTHROMYCIN can help prevent a secondary bacterial infection when used with API SUPER ICK CURE. If one fish is sick in an otherwise healthy community of fish, you should separate the diseased fish from the others and keep in a quarantine tank until the sick fish exhibits signs of recovery.

Should I keep the bio bag cartridge out of the filter until treatment with API E.M. ERYTHROMYCIN is finished, or should I only take it out for a few minutes before treating the water for fungus?

It’s recommended that you leave the carbon or filter cartridge out of the filter for at least 24 hours for aeration. Products that are designed to remove things from your aquarium, such as filter media, will also remove dosed medication from your tank. For best results from medication, remove your filtration media as you dose.

I have a 5 gallon tank. How much API E.M. ERYTHROMYCIN should I use in my aquarium?

We recommend using half the packet of API E.M. ERYTHROMYCIN for a 5 gallon tank, and then adding the other half of the packet after 24 hours.

Can API E.M. ERYHTROMYCIN be used with fungus cure? I’m on my last round, but my fish still has white rods around its gills. All other lesions have cleared.

API E.M. ERYTHROMYCIN is safe for use alongside other API® products. API medications may be used in conjunction with each other safely, as long as both sets of directions for separate medications may be followed exactly. We would not recommend using more than two medications at a time unless you are certain of the diagnosis of multiple ailments, so that you can tell which medications are working or not working while troubleshooting a stubborn disease issue.

Can I use API E.M. ERYTHROMYCIN to treat any species of fish?

This API E.M. ERYTHROMYCIN may be safely used to treat all types of fish, with the dosage adjusted accordingly based on the gallons per aquarium.

Do I have to remove my bio-bag cartridge from the filter before using API E.M. ERYTHROMYCIN, or can I use it with working filtration?

It’s recommended that you remove any activated carbon or filter cartridges before adding API E.M. ERYTHROMYCIN to your tank to ensure maximum potency of the medication.

Clearing the Water

API offers reliable three-step filtration for tanks of all sizes with their FILSTAR XP Canister filters and wide variety of filter media. These powerful filters constantly circulate the water, trapping organic waste and odors, removing harmful ammonia and contaminants, and helping good bacteria to thrive in the tank.

    Healthy pets

    By customer on Sep 14, 2021

    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!

    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. 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 DeeJay on Mar 17, 2021

    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 tricia on Feb 24, 2021

    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 KHales on Jan 9, 2021

    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.
