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.

Great Product
Used this with focus to treat my saltwater fish. My fish are healthy today.
Robert Fleener –
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.

Read the directions and do your every 2 day water changes
My angelfish was pooping white strings, not eating and getting white cysts on her face. I first treated for ich and nothing was working but when I was told to treat with metroplex for hexamita. Sheâs eating again and pooping normal. Iâm so happy with this product. You use every 2 days, 2 little scoops and do that for 2 weeks. Iâm so thankful for this product!

Good product
I have used this as a premature aid for my fish. When l added new fish to my aquarium. I have never had a problem with it’s safeness. I do use garlic and seachem bonding agent to feed it to my fish as l can imagine it’s not great tasting to my fish lol but using garlic and waiting to feed them for a day helps them eat it. I have also used it on sick fish through out the years and it works great.

Really works.
This medication is great for ich. I got some new fish at the pet store and they were covered with white spots. In three days they were clear after using this. I have tried a lot of ich cures but nothing works like this.

Saved my fish!
I wish I knew about this sooner. It would’ve saved my previous fish.I have two fish with fin rot and one of them is completely healed! The other one is slowly getting so much better after about two weeks of using it. I’m beyond happy.
Darren Mc Dowell –
Miracle worker!
I don’t know what my fish had. Just knew they were sick by the fact that they were laying on their side at the bottom of the tank. Used this every other day after a 50% water change. Mixed with seachum focus. After an evening things looked better, after a week back to normal.
