Millenium 2000 Aquarium Pump

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

nstead utilize a wet/dry trickle filter with a very shallow layer of gravel merely for decoration and to cover the bottom pane of glass

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

If you have an unusually-shaped fish tank, such as a hexagonal, or extra high aquarium, try keeping one inch of fish for every 12 square inches (length times width) of aquarium surface area. Remember to allow for growth.

New-Tank Cycle (Ecological Break-in) Information:

Start with 25% of the total capacity of the aquarium in inches. Wait at least two weeks before adding more fish. Waiting three weeks is better. Do a 25% water change before you add new fish, not immediately after. Add in increments of 100% of the number of inches of fish the aquarium already contains (if you already have two inches of fish, only buy

They also produce much less heat than metal halide lamps.

There is no question that metal halide lighting is still (and probably always will be) the mainstay of marine reef aquarium lighting. However, we have rarely seen a reef aquarium lit by metal halide bulbs that did not require a chiller for success, unless the aquarium was located in a cool room or was equipped with some form of major ventilation system. PowerCompact bulbs allow many photo-receptive species to be kept without the intense heat produced by halides. Research has shown that many stony corals, clams, and other sessile species that depend on photosynthesis of zooanthellic al

Even with the smaller species you are still going to need a rather large aquarium. The tropical gar also is possible to keep in aquariums as it doesnt grow as large; however this species is very hard to find. The Cuban gar is a red-list endangered species and shouldnt be kept even if you somehow find one.

In aquariums gars are quite demanding and r

Shelldweller from Lake Tanganyika

Lamprologus ocellatus

There are several species of shelldwellers in lake Tanganyika, but this one is definitely my favorite, Lamprologus ocellatus. Shelldwellers are maybe not the most colorful fish form the lake but .
