## Description

Fritz Maracyn - for Saltwater and Freshwater gram-Positive Relief from Bacterial gil, Popeye, More - Easy dose Packets, 20 Count

Review: Helped save most of our fish - Was very happy to get this,though we were disappointed that it took so long to get to us in Downeast Maine. We ended up losing a few fish before it arrived. Sometimes our shipments are delayed by a week or more,which normally wouldn't matter,but in this case it did. The product did however save our remaining fish and our snail Wendell didn't seem to suffer any ill affects from being in the tank with the treated fish. I would highly recommend ordering this before you have an actual problem so you have it on hand to start treatment immediately, unless you live in a more metropolitan area that gets deliveries within a day or two.
Review: Best - Great value for money. This is one of my go-to medications for my tank. The fish seem healthy and the quality of the medication is sprayed. Color is consistent and as long as you don't eat it, it's safe.

Great value for money. This is one of my go-to medications for my tank. The fish seem healthy and the quality of the medication is sprayed. Color is consistent and as long as you don't eat it, it's safe.

### ⭐⭐⭐⭐⭐ Effective, low cost, easy to use
*by L***N on December 14, 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.
