Using an undergravel aquarium filter is one of the oldest methods of attaining biological filtration in fish tanks. This technique is employed when you want to keep your underwater friends happy and healthy without going through all the trouble of frequent cleaning and changing of water.
When deciding to go for this type of under filter, your aquarium design will involve the use of rocks, stones, or gravel instead of sand. These will then be held suspended on top of the filter plates so as to maintain some space underneath the setup for filtration purposes. With this type of device, waste products from fish and leftover food are sucked and absorbed through the gravel flooring before being filtered and cleaned.
The best undergravel aquarium filter also works in promoting proper circulation of water not only underneath the gravel, rocks, and stones but in keeping the entire underwater environment fresh and clean for its habitats. The aquarium filter reviews found below will serve as your guide to finding the right model for your aquarium setup.
