Nitromax Marine 16 oz
I know some hobbyists disagree on biological additives sometimes. However, this one really works, if you're setting up a tank for the first time, or just using it for maintenence, it works. When I set my tank up my friends were shocked at how fast my tank cycled. And I've never had a problem since, I've tried other products, but this one works the best for me.

I have used Nitromax Marine since day 1, it is an essential part of my aquarium maintenance.
