There are many options available now for illuminating an aquarium, but they all fit conveniently into two categories: fluorescent and metal halide. Within these two categories there are a few different formats, and plenty of bulbs to choose from.
Forms of lighting that are not recommended for reef tanks include some mercury vapour and sodium vapour lights, as well as HQL and HQI-NDL lighting which have colour temperatures (4300 K) and spectrums that aren t ideal. These lights can be used successfully for reef aquariums, provided UV emissions are blocked and temperature is managed. With 4300 K light, the colours of the animals and appearance of the tank is not as good as with daylight spectrum, but most corals will still grow as long as they receive bright light. Quartz halogen lights that are inexpensive and readily available from hardware or department stores are also unsuitable because of the spectrum and the tremendous amount of heat they produce.

The word aquarium originates from the ancient Latin language, aqua meaning water and the suffix rium meaning place or building. Aquariums are beautiful and look good anywhere! Home aquariums are becoming more and more popular, it is a hobby that many people are flocking too and fish shops are on the rise. Fish are generally easy to keep although do they need quite a bit of attention. Puppies and kittens were the typical pet but now fish are becoming more and more frequent in house holds. In recent years fish shops have noticed a great increase in the rise of people wanting to purchase aquariums and fish, the boom has been great for local shops as the fish industry hasnt been such a great industry before now.
