Filtration is one of the most important parts of a reef aquarium. Stable systems rely on biological, mechanical, and sometimes chemical filtration working together to maintain water quality.
Biological Filtration
Biological filtration is the foundation of a reef tank. Beneficial bacteria convert harmful waste into less toxic forms and help keep the aquarium stable.
Mechanical Filtration
Mechanical filtration removes particles and debris from the water. Filter socks, filter floss, and other materials are often used for this purpose.
Chemical Filtration
Chemical filtration may include carbon or other media used to remove impurities and help improve water clarity.
Filtration Strategies
Different reef systems use different approaches. Some rely heavily on live rock and skimming, while others include sumps, reactors, and additional filtration equipment.
System Balance
Good filtration is not about using the most equipment. It is about balancing the needs of the aquarium and supporting long-term stability.
Final Thoughts
Filtration works best when it is planned as part of the whole system. Understanding how the different parts work together helps reef keepers build healthier aquariums.
