Frequently Asked Questions
What kind of stuff does Mardel Maracyn help with? +
I’ve used Mardel Maracyn for fin rot and that white, fuzzy stuff on fish. It clears up most of those common bacterial things pretty quick.
How do you dose Mardel Maracyn? +
The packets are already measured out. I just drop one in per day based on my tank size. Honestly one of the easier fish medications to use.
Is Mardel Maracyn okay for beginners to use? +
Yeah, totally. It’s simple and works without needing to mix anything. That’s why I keep it around—one of the few best fish medications I’ve actually reused.
Can you use Mardel Maracyn with other treatments? +
Sometimes, but I usually don’t. I stick with just Mardel Maracyn unless I’m sure it won’t mess with anything else in the tank.
How long before Mardel Maracyn works?+
Usually by day 2 or 3 I start seeing fish perk up. If not, I’ll finish the 5-day course and see if it helps before trying something else.
