I did struggle with ammonia levels for about 2 weeks after the treatment, I used Prime to detoxify, added bottled bacteria and did small water changes every couple of days. Now everything is back to normal ### ⭐⭐⭐⭐⭐ Effective, low cost, easy to use *by on Reviewed in the United States 14 December 2024* After much research I discovered my Tetras had mouth rot. It is a bacterial infection. This product was recommended by the local pet store's Aquatic Specialist. I checked the reviews on Amazon as well. Maracyn received 4 and 5 star reviews. This product was much cheaper on Amazon compared to the local pet store. Maracyn treats a broad spectrum of gram positive infections. This product comes in pre measured packs. Each pack treats 10 gallons. No measuring and no mess. No worry about over or under dosing your fish. You have to remove all chemical filters before treatment. Maracyn will make your water cloudy. This product also strips your bio filter of good bacteria. You have to use an ammonia reducer (like Prime) because ammonia levels can spike during treatment. Keep an eye on your water. Test your water during treatment. I feel these are minimal side effects to ensure healthy fish. After day 3 the mouth rot was gone. I will complete the 5 day treatment plan as directed. Day 6 you do a 25% water change. Use all new filter media, including chemical media. I use Seachem Stability and Seachem Prime to cycle my aquarium faster, and establish my bio filter. I am very pleased with the results of Maracyn. It treats a broad range of gram positive bacterial infections. This product is easy to use. It is effective. By buying Maracyn on Amazon you will save money. I would highly recommend this product. ### ⭐⭐⭐⭐⭐ good product *by on Reviewed in the United States 25 July 2026* came in quickly used it with my quarantine tank. no problems ## Frequently Bought Together - Fritz Maracyn - for Saltwater and Freshwater gram-Positive Relief from Bacterial gil, Popeye, More - Easy dose Packets, 20 Count - Hikari USA Inc.
