How To Choose An Aquarium Hood.
There is an increasing trend for aquariums to be purchased as a complete kit where all components, including the hood or lid are an inclusive and integral part of the package. The option remains, however, for an aquarium system to be assembled from scratch from off the shelf components to create an individual size, shape or style which is not offered by the manufacturers of systemized aquaria. Some aquarists may also be in possession of an older aquarium, which is in need of a re-vamp, and for these purposes a range of aquarium hoods are available.

Why Do You Need An Aquarium Hood.
An Aquarium Hood, apart from finishing off the look of the aquarium by being of the same or a complimentary finish, also has several functions. It will house the fittings for a light system, will stop fish from jumping out of the aquarium and stop the cat from getting in. It will also keep out dust and other air borne pollutants that may be detrimental to fish.

Types Of Aquarium Hood.
Aquarium Hoods are available in a range of standard sizes by a number of manufacturers. Non-standard sizes are often available to order by quotation. Aquarium hoods are usually made from metal, plastic or wood. Metal hoods are commonly powder coated aluminium, the coating providing a decorative exterior which also is resistant to corrosion. Plastic hoods are often injection moulded and this process produces an inexpensive product but which may be a little flimsy. Wooden hoods are usually made from a veneered M.D.F. or fibre board and available in many different colours and wood finishes. Solid wood hoods are also on the market but great care must be taken when choosing a solid wood unit as, unless correctly built and finished, solid wood will warp when subjected to the rising heat and moisture from the aquarium beneath. A basic hood will offer very little in the way of features whilst a more deluxe and little more expensive version will provide extra features such as compartments to conceal lighting switch gear and feeding / access flaps as well as a more furnished look.

Choosing An Aquarium Hood.
When choosing an aquarium hood firstly measure your aquarium length and width accurately. Most aquariums (UK) are standard sizes of lengths 30, 45, 60, 75, 90 or 120 centimetres and widths of 20, 25, 30, 38 and 45 centimetres. Decide whether or not lighting is required and choose a hood that will allow for this option if necessary. Choose a hood with an external finish that will best compliment the aquarium and stand as well as the room décor. Avoid using aluminium hoods on marine systems as this material produces toxins when in contact with salt water.

If you have a metal hood and are not sure of its metallic composition, you can make it safe by applying 3 coats of a good quality polyurethane lacquer, ensuring each coat is totally dry before applying the next.
