Filtration Options - Mechanical, Chemical, Biological Filters
Filtration is an essential aspect of maintaining a healthy and thriving reef aquarium. It involves the removal of waste particles, toxins, and harmful substances to create a clean and stable environment for the inhabitants. There are several filtration options available, including mechanical, chemical, and biological filters. In this article, we will explore these options in detail.
Biological Filtration
Biological filtration, often considered the most crucial aspect of reef aquarium filtration, relies on beneficial bacteria to convert harmful ammonia and nitrite into less toxic nitrate. This process occurs naturally in any established marine system but can be enhanced through various means:
Biological filtration, often considered the most crucial aspect of reef aquarium filtration, relies on beneficial bacteria to convert harmful ammonia and nitrite into less toxic nitrate. This process occurs naturally in any established marine system but can be enhanced through various means:
1. Live Rock and Sand: These porous materials provide ample surface area for beneficial bacteria colonization. The organisms present within the rock and sand help break down organic waste, converting it into less harmful substances. You can acquire live rock from your local fish store, online retailers or fellow reefers.

Refugiums: These separate compartments within the sump or filtration system allow for the cultivation of macroalgae and other microorganisms that aid in nutrient export by consuming nitrates and phosphates. Growing algae in a small tank connected to your main display can also aid in diversity and can help stabilize Ph. |
3. UV Light Filters: Ultraviolet (UV) sterilizers use UV light to destroy or inhibit the growth of pathogens, parasites, and algae spores present in the water column. They are particularly useful when dealing with persistent outbreaks or preventing fish diseases from spreading in a closed aquarium environment.
Mechanical Filtration
Mechanical filtration primarily focuses on removing solid debris such as uneaten food, fish waste, and other particulate matter from the water column. This process helps prevent the accumulation of organic materials that can lead to poor water quality and potential health issues for the marine life. Mechanical filtration can be achieved through various methods:
Mechanical filtration primarily focuses on removing solid debris such as uneaten food, fish waste, and other particulate matter from the water column. This process helps prevent the accumulation of organic materials that can lead to poor water quality and potential health issues for the marine life. Mechanical filtration can be achieved through various methods:
1. Protein Skimmers: These devices utilize foam fractionation to remove dissolved organic compounds (DOCs) from the water by creating fine bubbles that attract and collect these molecules. Protein skimmers are highly effective at reducing nutrients in the aquarium, which in turn helps control algae growth and promotes better water clarity. 2. Filter Socks: These mesh bags or sleeves trap larger debris before it enters the main filtration system. They act as a pre-filtering mechanism that prevents clogging of other filter media while also improving overall water quality. |
Chemical Filtration
Chemical filtration involves using specific media to remove dissolved impurities, toxins, and chemicals from the water. The goal is to eliminate harmful substances that may negatively impact the health of your reef tank's inhabitants. Some common chemical filtration options include:
Chemical filtration involves using specific media to remove dissolved impurities, toxins, and chemicals from the water. The goal is to eliminate harmful substances that may negatively impact the health of your reef tank's inhabitants. Some common chemical filtration options include:
1. Activated Carbon: Activated carbon is widely used in reef aquariums due to its exceptional adsorption properties. It effectively removes organic compounds, medications, chlorine/chloramines, and various toxins from the water column. 2. Chemical Absorbers: These filter media specifically target certain elements or compounds like phosphate removers (to combat excess phosphates), nitrate absorbers (to reduce high nitrate levels), or specialized resins to tackle specific issues related to water chemistry. |
It is important to note that a combination of these filtration methods is often necessary to achieve optimal water quality in a reef aquarium. Each type serves a specific purpose and contributes to maintaining overall stability and health for the tank's inhabitants.
Regular maintenance, including cleaning or replacing filter media as needed, monitoring water parameters, and performing routine water changes, is vital to ensure effective filtration over time. Additionally, understanding the needs of your specific reef ecosystem will guide you in selecting the appropriate filtration options for your setup.
