Lights Out!

Running a salt water aquarium is educational, very satisfying, and mostly relaxing. Mostly relaxing is correct, there are those occasions when the word ‘relax’ doesn’t apply. For example, when a pump fails and the shops are shut, when a fish is lost etc. There is also another occasion that aquarists dread, and that is a power supply failure.

Natural Aquarium Lighting

The great majority of aquarists light their aquariums with halide bulbs or fluorescent tubes or a combination of both.

Huge strides have been made in the manufacture of suitable lighting for aquarists. There is a wide choice of Kelvin (K) rating in both fluorescent and halide, and a choice of power (W) at least in halides, though there are T8’s, T5’s and power compacts in fluorescents. Science produces as near as possible the light needed by reef life.

Using a UV sterilizer in a reef tank

What is the sterilizer? It is a container, usually in a near tube shape, in which an ultraviolet (UV) fluorescent lamp is contained. The lamp emits light at around 254 nm. The lamp is constructed of quartz glass to prevent the UV being absorbed as it would be if ordinary glass were used. The lamp is in a container of its own to shield it from the water, and then there is an outer container. The space between the containers is very small allowing full penetration of UV light. The water is passed between the outer and inner containers by a pump or power head.

DIY aquarium backgrounds
