nutrient) elimination. I eagerly await the commercialization of these units.

My respect is not so great for anaerobic denitrators. Denitrification is just what it appears to be; a reverse of the biological processes weve gone over called nitrification, with nitrate being converted back to nitrite, ammonia and finally nitrogen gas. This feat is accomplished by other bacteria species that thrive in the absence o

The other interesting option with these powerheads is the needle wheel that is included to regulate the injection of air into the water stream coming from the pump. While this is kind of neat, it is not really that useful or necessary. I generally forgo the air injection in all marine setups because the bubbles bursting at the surface of the water creates far too much splash and salt spray for my liking. A

Heres my take on the most common paths.

Rationale: Who Are These Guys, Why Do I have To Know About Them?

A short version of the story: Fish and invertebrate livestock produce ammonia (NH3) as their principal excretory product This material is unfortunately quite toxic to them and its too expensive, inconvenient to remove it by dilution, chemical filtration. Happily, there is a group of microbes/bacteria tha

There is usually a control valve for regulating water flow. A check valve is usually placed on the filter intake to prevent the sand from packing-down when the filter is turned off.

Because water flows upward through the filter, the sand in the filter becomes suspended or "fluidized" in the water column, forming a fluidized bed of sand. If the flow of water is controlled properly, the sand does not flow out of the filter, but remains suspended. This happens because the flow of water is just fast enough to keep the sand in suspension. The weight of the sand prevents it from escaping the filter. Because the sand is suspended in wat

The males are larger and more colorful than the females. The male becomes very brightly colored at spawning time. Their nature and needs of treatment are similar to those of the pearl gouramis, they will eat anything they are being feed, however they prefer live foods and prepared mixtures. Best spawned in a separate aquarium especially setup for this purpose. Place a well-conditioned pair into a 40-liter or 60-liter, thickly planted aquarium with a lot of floating plants. The spawn can consist of 300 to 700 eggs. After spawning is completed, the female should b

Blue Algae ( cyanobacteria )

Most aquarium hobbyists know and fear this type of algae, well actually it's the organism cyanobacteria. The appearance of the blue algae is often a slimy blue green carpet, quickly spreading.

Where to place my Zoa's??
I was wondering how much light most Zoa's need. I am thinking of putting the new frags lower in the tank, right on the sand bed or just a little above. I have a 26" deep tank and I am using 250W MH and pc Actinics for lighting. I have some zoos that are doing fine in the mid section of the tank and a large colony that is quite near the surface that is al.
