## Overview

The formula is gentle on beneficial filter bacteria and safe for invertebrates when used in medicated food mixes. Easy to dose either directly into water or combined with food, MetroPlex ensures comprehensive parasite control with minimal risk of overdose, making it a trusted choice for professional and hobbyist aquarists alike.

## Description

MetroPlex is an effective and safe treatment for several protozoan and anaerobic bacterial diseases of fish (Cryptocaryon, Hexamita, Ichthyophthirius). It does not adversely affect the filter bed and is easily removed with carbon. It can either be dosed into the water or combined with Focus in a medicated food mix. It will treat both internal and external infections regardless of the delivery method. When used in a medicated food mix, it is excellent for treating parasites in tanks that contain invertebrates. MetroPlex is gentle and there little danger of overdosing.

Review: Super easy to use and very effective, just takes a little prep time. - I use this product in conjunction with Seachem ParaGuard to treat all new fish I receive into my fish room. What I find works best for me is doing a 30%ish water change around 4;00 pm. Around 5:30 I prepare my Metroplex food. gather about what you would normally feed your fish into a small bowl. In my case, I use a frozen cube of bloodworms, small pinch of flakes and about 1-2 ml to the bowl and of course one serving of Metroplex. I wait until everything melts, and I stir occasionally. about 6:00 pm I feed my fish the food. I have read stories of fish refusing to eat food with metroplex, so some people recommend GarlicGuard and Unity. Garlic guard makes the food all but irresistible to the fish, and unity, binds the medication to the food so it does not escape into the water column. None of my fish have ever rejected the food with metroplex without any other additives, and they tend to inhale it so quickly that a vast majority of the medication is ingested by fish, so I don't need Unity or GarlicGuard unless my fish is refusing all food, medicated or not.
Review: Very good product for Cichlid parasites - Very good product for Cichlid parasites; arrived as promised.

## Questions & Answers

**Q: What are the ingredients and % of ingredients?**
A: package reads:
active ingredient: metronidazole 70%
inactive ingredients 30%

**Q: Is this liquid or powder**
A: Powder

**Q: What are the inactive ingredients?**
A: Per the Seachem MSDS , only 70% by weight is actually metronidazole.  The spoon included holds 125mg.  The rest of the inactive ingredients are "trade secrets", but excipients.  If I had to guess, I'd say magnesium stearate, one of them most common and added to other white powders.

**Q: Is it safe for plecos?**
A: Did not hurt my Pecos or any other fish it is all safe

Very good product for Cichlid parasites; arrived as promised.

### ⭐⭐⭐⭐⭐ It Works
*by B***N on March 9, 2026*

The Seachem MetroPlex Metronidazole Parasite and Bacterial medicine is the most effective treatment for those diseases that I've used. I have an African Cichlids, and a large male was suffering from what I thought was internal parasites. I tried the other treatments I had on hand, but they weren't working and I was sure he was going to die. I treated him for about 10 days with the Seachem, he started to get his color back and he started acting better. A few days later he began to eat. It works!
