Como hacer un filtro externo tipo canister para acuario

In the world of aquariums, a filter is a mechanism whose purpose is to circulate aquarium water and pass it through specific filter media to remove impurities and ensure it is biologically purified before returning to the tank. Filters are essential in aquariums, as they remove waste produced by fish and other aquatic animals, as well as uneaten food and/or aquatic plants that sometimes appear. The main component of these filters is the water pump, which circulates the tank water through the various filter media with different porosities and functions. Cleaning the aquarium is very important because it ensures the health of the fish and keeps their ecosystem free of impurities and other threats that could harm them. Different filters exist depending on the aquarium's characteristics; basically, we can distinguish between two types: external and internal. Foam foam: a porous material responsible for retaining larger debris. Synthetic fiber or filter floss: retains smaller and finer debris. Activated carbon: Its function is to retain microscopic particles, as well as eliminate medication residue, the yellowish color of the water, and any odor it may produce. Ceramic: It is used as a biological filter, since the beneficial and essential bacteria of the aquarium reside in its numerous microscopic pores to eliminate toxic substances contained in the water (ammonia, nitrites, and nitrates).
