Let me start by saying this: Seachem MetroPlex is the MVP of my aquarium meds cabinet. When my fancy goldfish started doing the dreaded 'sideways float' at the bottom of the tank, I panicked - until this powder came to the rescue.
The magic happens when you mix it with Seachem Focus to create medicated food. Pro tip: Use frozen bloodworms as your base - fish go crazy for them! I saw improvement within 24 hours, and by day 7, Mr. Bubbles was back to his photogenic self.
What I love? It's reef-safe (tested on my coral tank) and doesn't nuke your biofilter like some meds do. The powder form lasts forever compared to liquid treatments. Bonus points for working on both freshwater and saltwater setups.
The only con? Some picky eaters might turn up their fins at medicated food. Solution? GarlicGuard works wonders here - turns their medicine into gourmet dining.
After three years of fishkeeping, this is the one medication I always keep stocked. When fish emergencies strike at 2 AM (because they always do), you'll thank past-you for having MetroPlex on hand.
