Mechanical and Chemical Filtration

Back when I started keeping fish, filtration consisted of angel hair or glass wool as the mechanical filtration and charcoal as the chemical filtration. Now there are a multitude of ways to perform these types of filtration, but rarely are their merits or shortcomings discussed.

Instead, the main focus is on protein skimming, probably as a result of there being significantly more marketing of protein skimmers than other forms of filtration. This is unfortunate as when done properly mechanical and chemical filtration are still fundamental aspects of filtration and are crucial for the long-term success of a reef tank. When neglected, these types of filtration can produce negative consequences for a reef tank and its inhabitants. But when done right each type of filtration helps the other types of filtration work better and makes the tank more successful over the long term.
