Each fish also limits the growth of the other fish by secreting growth-limiting hormones (GLH) into the water, which explains why some fish grow more rapidly than others.

Unfortunately, if a tank is overcrowded, fish that grow large in the wild will become deformed, as bone growth often exceeds muscle growth when oxygen levels arent high enough. Other fish are simply crowded out and die "mysteriously." This happens frequently in saltwater aquariums that are overstocked

The water at the bottom of the filter is fresh and high in dissolved oxygen, so aerobic bacteria cultivate in the bottom half of the sand bed, and remove ammonia and nitrite, using up oxygen in the process. In taller fluidized-bed filters, enough aerobic bacteria cultivate in the bottom half so that as water flows past them, they remove most of the oxygen from the water, so facultative anaerobic bacteria cultivate in the top half of the sand bed where they remove nitrates. Not all fluidized-bed filters are tall enough to promote anaerobic denitrifying ba

The plenum method was discovered by Dr. Jean Jaubert and is often referred to as the Jaubert System. "Plenum" refers to an un-oxygenated layer of water trapped beneath a deep layer of gravel or sand at the bottom of an aquarium. This layer of water becomes anaerobic. Bacteria cultivate in this oxygen-free environment and remove nitrates from the aquarium. There are several variations of the plenum, depending on what literature you read.

The basic structure of the plenum system is essentially a deep (3" to 4") layer of gravel, suspended 1/2" to 1" above the bottom of an aquarium. It is usually recommended that very little

If "Brand B" does not perform quite as well, but is affordable, always in stock, is well supported by the manufacturer and can be sold for a respectable profit, many more retailers will choose to carry it.

Hang-On & Integrated Wet-Dry Filters: Some wet-dry filters are designed to hang on the back of the aquarium. These are useful only for smaller aquaria, or in situations where there is no space below the aquarium for a true wet-dry filter. In most designs, more than half the media is submerged, which is a major drawback. They also do not have the capacity of a normal wet-dry,
