Filters
aquarium filters play a crucial role in maintaining water quality and ensuring a healthy environment for fish and other aquatic inhabitants. There are various types of aquarium filters, including hang-on-back filters, sponge filters, and submersible filters, each with its own unique mechanisms and benefits. Hang-on-back filters are external filters that hang on the back of the aquarium. They typically consist of a pump that draws water from the tank, passes it through filter media (such as sponges, ceramic rings, or activated carbon), and then returns the filtered water to the tank. Sponge filters consist of a porous sponge that serves as a mechanical and biological filter. They are powered by an air pump that drives water through the sponge, trapping debris and providing a surface for beneficial bacteria to colonize. Submersible filters are placed entirely underwater in the aquarium. They often contain filter media, such as foam pads or activated carbon, and a pump that circulates water through the filter to remove impurities.
