Choosing an aquarium

How big should your aquarium be? Aquariums come in many shapes and sizes. It is
advisable to choose an aquarium that is at least 10 gallons/ 40 L, since small aquariums
are much more difficult to maintain. The waste build up in small aquariums is quick and
quite large in comparison with a larger aquarium. A small aquarium will therefore require
very frequent water changes. Changes in temperature or water chemistry will also take
place more quickly in small aquariums. Rapid changes in the temperature or water
chemistry are harmful for fish.

 
I would recommend a 30-gallon/120 L aquarium to novice aquarists, since this will
provide enough room for more fish and is easier to maintain as it has enough water
volume to dilute fish waste. A larger aquarium will naturally be even easier to maintain,
but the benefits of an aquarium that is larger than 30-gallon/120 L is not as significant as
the difference between a 30-gallon/120 L aquarium and a smaller one. A 30-gallon/120 L
aquarium is large enough to buffer against to rapid changes in water values. 30-
gallon/120 L is therefore an ideal beginner size.

Fish aquariums come in many shapes ranging from rectangular to hexagonal or even
cylindrical. While making your purchase, it is not only the beauty of the piece that
counts. Mundane matters like how easy it will be to clean out the aquarium regularly, and
how to keep all the nooks and crannies hygienic are important considerations.

The height of the aquarium is also a very important aspect. An aquarium that is very deep
is complicated to keep for the beginner aquarist. Increased height means greater difficulty
when cleaning and your aquarium might therefore always carry some amounts of waste
even after a thorough clean up. Poor light penetration is another problem with a deep
aquarium. Plants will not thrive in water that has poor light penetration and special
lighting is therefore needed in deep planted aquariums.

Acrylic or Glass Aquarium

Glass aquariums usually cost less and do not get scratches as easily as acrylic aquariums.
Glass aquariums are also stronger, as they are bonded together by a silicone sealant. They
need support only on the edges, unlike acrylic aquariums. Glass aquariums are very
durable, and can last for many years without any problems. Proper lighting will make
glass aquariums look almost as clear as acrylic ones. On a negative note can be said that
glass aquariums are always much heavier than acrylic.

However, if you are looking for irregular shapes, than these are easier to obtain as acrylic
aquariums. Acrylic aquariums are much clearer than glass, and have better insulation.
This means that you can use a smaller heater in your aquarium to maintain the proper
temperature. Acrylic aquariums do however scratch easily and can therefore only be
be quite a troublesome procedure.

The price can also be an important factor when it comes to buying your first aquarium.
Glass aquariums are usually the cheaper alternative and there is also a wider selection of
second hand glass aquariums than there is of second hand acrylic aquarium since glass
aquariums are more durable.

Putting the aquarium in place

When you have selected the best aquarium for your needs, it is time to take it home. Here
is a checklist that you need to consider:

Look for any scratches on the aquarium before you make
the purchase.
Test to see if there are any leaks in the aquarium.
Take care not to load any heavy items inside the aquarium
while you carry it home. This may lead to scratching or even
breakage.

Get a tight fitting hood for the aquarium when you buy it. An open aquarium is never a
healthy option. More water will evaporate form an aquarium where the water is open to
sunlight, heat etc. Evaporation will lead to the water becoming concentrated with waste
and animal- and plant debris, and can also cause water damages and mildew in the room
around the aquarium. Contamination from falling waste is another problem. With an open
aquarium you will also risk casualties since fish often jump out of an open aquarium, and
ending up on the floor is more often than not fatal for the fish unless you immediately
spot it and put it back in the aquarium. Thus an aquarium needs a good and sturdy hood.
These hoods come in various decorative shapes and colors.

There are various accessories that go with your aquarium, other than the hood. An
aquarium is a complete set of a number of equipment that works together.

Choosing equipment

Lighting


The first equipment that you will come across is probably the lighting for the aquarium.
Most hoods come with fluorescent or incandescent lighting. Fluorescent bulbs are a better
choice despite the fact that they are a bit more expensive since they have long-term
benefits. 
 
They burn cooler, thereby not affecting the water temperature at all. Fluorescent
bulbs have another benefit as they uses less electricity. Fluorescent bulbs can be
purchased in sizes that cover the entire aquarium. This will provide even lighting in all
areas of the aquarium. There are a wide variety of fluorescent bulbs that emit different
spectrums of light. Some of these will even assist plant growth. Some will lead to an
increase in algae growth. Optimal plant growth requires a particular wattage, which can
be decided by the size of the aquarium. Usually, 1 gallon of water will require 1.5 watts.
