## 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

*by R***R on October 5, 2023*

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.
