nabokovfan87 Posted August 14, 2022 Share Posted August 14, 2022 API: Quote For each 10 gallons of water, empty one packet directly into aquarium. Repeat dose after 24 hours. Wait another 24 hours then change 25% of the aquarium water. Repeat this treatment for a second time, for a total of 4 doses. Then make a final 25% water change and add fresh activated carbon or replace filter cartridge. Fritz: Quote Directions: One complete course of treatment will take 5 days. Treat for the full course of treatment even if visible signs of infection or illness disappear.Day One through Day Five: Each day add contents of one packet per 10 gallons of water to be treated.Day Six: Perform a 25% water change. If Necessary, a second full course of treatment may be performed starting on Day Seven. Any idea why there's a difference of treatment on these two? I am planning to dose every day, but I was curious why the API one was different when I looked it up. Lower stress on the fish I would imagine, but is there something I'm missing? 1 Link to comment Share on other sites More sharing options...
Colu Posted August 14, 2022 Share Posted August 14, 2022 If I remember rightly API erythromycin has 400mg of the active ingredient and maracyn has 200mg that could be why they have different dosing instructions Link to comment Share on other sites More sharing options...

only6foot6 Posted April 4 Share Posted April 4 Reviving this old thread from the dead. I had the same question - Why do Maracyn and API Erythromycin have different treatment plans? They both have 200 mg Erythromycin per packet per 10 gallons Maracyn - 5 days straight, water change on day 6 API - 2 days of treatment, do water change, 2 more days of treatment Which one is better?

Tony s Posted April 4 Share Posted April 4 (edited) @only6foot6 I’d follow the directions on packing. Sometimes it’s not the med, it’s the carrier or binding agent. We see this with livestock meds. They will have different usda instructions from different manufacturers, even though it’s the same drug in the same amount. It can even alter medication withdrawal times.

only6foot6 Posted April 5 Share Posted April 5 @Tony s - Interesting regarding the carrier / binding agent. I wouldn’t have thought of that. To your point, sticking with the individual’s treatment plan is probably the best. Thank you. Link to comment Share on other sites More sharing options...
