There are three types of Saltwater Aquarium Filtration:
Mechanical - removes particles from the water
Biological - provides areas for helpful micro-organisms to
live
Chemical - changes water quality by adding oxygen or
removing ammonia
In saltwater tanks, mechanical filtration is much more important, which is why
protein skimmers have increased in popularity. Saltwater filtration has
evolved through a number of stages. The first breakthrough was the
development of the underground filter. Next came the trickle filter.
These have both been superceded by the protein skimmer in combination with live
rock. More information on saltwater filters is provided through the
following links:
Remember to place a loop in filter electrical cords, as this will cause
any water to drip on the floor instead of entering an electrical outlet.
A
Ground Fault Interrupter is always a good idea with electrical equipment
that can come in contact with water.
