Free Fish Aquarium

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

Because of this I rarely use them, but they do have a couple of interesting options that are worth mentioning.

These pumps can be purchased with a kit to use them in a reverse flow undergravel filter. In a conventional undergravel filter, water is pulled down through the gravel, under the filter plate, and up the lift tube. In this mode the beneficial bacteria in the substrate act as a biological filter, while the substrate itself acts as a crude mechanical filter as it traps dirt and debri

Modern filter plates, commercial and custom-made utilize chemically inert materials to provide continuous, even flow through the whole systems base. The best incorporate large (one inch plus) air-lift, powerhead and pump driven mechanisms. (photograph).

There is nothing wrong with airstone-only driven systems. These move a goodly volume of water, with the added benefit of increased gaseous diffusion; while not adding extra waste heat. Air pumps are the "lowest-cost" provider of water movement.

" These bulbs operate in the same way as regular fluorescent bulbs, except that the ballasts that power these lamps apply more electrical current to the lamp, and some brands of VHO lamps employ more phosphors in their operation. Typically, a VHO bulb produces twice the output in lumens as a regular fluorescent bulb. They also tend to burn twice as hot as regular fluorescents, a

A female usually lays 1,000-2,000 eggs. The eggs are opaque at first, turning transparent in 24 hours. After the eggs are laid, both parents watch over the eggs, wafting the eggs with their fin and guarding them against predators. Occasionally they take the eggs in their mouth, which keeps them clean and turns up bad eggs, which are then destroyed.

If a constant tank temperature is maintained, the eggs should hatch in abou
