## 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.
