Media Configuration & Customization

Out of the box, the manufacturer ships the unit primarily with basic mechanical media: a coarse prefilter sponge and fine white filter floss.

Because it lacks biological media from the factory, you will need to customize the baskets: [1]

Bottom Basket: Best utilized for mechanical layers (the factory coarse sponge) to catch large floating debris.
Top Basket: Best packed with highly porous biological media (such as ceramic rings, sintered glass, or volcanic stone) to cultivate beneficial nitrifying bacteria. Top this off with the fine white filter floss to polish the water right before it returns to the tank.
