Under Gravel Filters
Under Gravel Aquarium Filter
Let's face it. People want their aquariums to look nice! The beauty of water and aquatic life is what draws so many people to the hobby in the first place. Under gravel aquarium filters are perfect for fish owners who want to oxygenate and clean their tanks without having a big clunky filter ruining the aesthetic.
One of their significant advantages is how much surface area they provide for beneficial bacteria to grow. Because under gravel filters are for use with gravel only, as the uplift filter pushes out bubbles, healthy bacteria spread and have plenty of room to grow. And if you're breeding fry to feed your fish, you don't have to worry about them getting sucked into the filter.
