Which Is The Best Filter Media For Freshwater Aquarium?
Every fish tank needs a filter to carry out filtration and keep the water clean. Filtration is a process that aids in removing contaminants including excess food, floating dirt particles, various chemicals, bad odor, fish waste products from the water.
Filtration is necessary for every type of aquarium as it keeps the water clean which is important not just for the look, but also to keep the inhabitants healthy and safe. Filters do this by removing contaminants and increasing the amount of oxygen in water by maintaining a regular water movement.
Mainly, 3 kinds of filter media are used to carry out filtration. These include biological, mechanical and chemical. Each serving a different yet vital purpose. Let’s talk about each in detail:
This type of filter media is necessary in all types of aquariums. This is because all fish produce waste which can turn into toxic ammonia. Other than that, decaying matter, dead fish and various other biological bodies can produce toxic waste that can be harmful for the habitants.
Biological filtration converts this toxic ammonia from waste into nitrite and then nitrite to nitrate. NItrate doesn’t harm the fish, however, it still needs to be extracted out from the water which is done by filtration.
Biological Filter Media Types: Ceramic rings, bio balls, pallete, foam etc.
Mechanical filtration involves passing the aquarium water through a mechanical filter media that acts as a strainer and catches dirt particles that are in the water and lets the clean water pass through.
Mechanical filter medias are of various types and qualities. The finer the quality, the more particles it can trap.
Mechanical Filter Media Types: Sponge, filter pads, gravel, filter floss, air bubble dense mass etc.
This type of filtration is involved with extracting toxics and poisons from the water with the help of activated carbon filter and chemical resins. Around 2 gallons of water can be chemically filtered every month using a cubic inch of carbon filter.
Chemical Filter Types: Activated carbon, algone, ion exchange etc.
Without further ado, let’s have a look at the best filter media for freshwater aquarium:
