Starting A Marine Aquarium - The Very First Considerations

Seeing pictures of a healthy marine fish only or reef aquarium in books or on the internet, or even better, in reality at a public aquarium will cause just about anyone to appreciate the beauty and general fascination of them. Some people will wonder if they could have one, and the thought will shortly disappear. Others, however, will not forget so easily and will want to delve further into the possibility of having their own home aquarium.

If the potential aquarist knows a friend who already has a healthy marine aquarium, then there is a source of advice available already. The friend will already have been through all the research and considerations. Often, however, the potential aquarist will want to find out for him/herself. That is very good, as the aquarium system will be understood thoroughly. Then there may not be a known marine aquarist available, so what is the first move? Dashing to the local shop and buying an aquarium and a few bits of equipment that the shop says is needed is totally incorrect.

The first move is to follow a planning scaffold. This scaffold will be the foundation for all the decisions that need to be made in building the system. There are quite a few decisions along the way and things can get a little confusing, even to someone who is experienced in the freshwater aquarium field. The scaffold will help.

The scaffold has to prepare the budding marine aquarist so that indicative costing on basic equipment provision can be made. Often marine aquarists have equipment laying about. This could have been caused by upgrading because the original equipment was not adequate and needed to be replaced. Money expended that perhaps need not have been.

So, the scaffold then. The following is a list of headings and basic notes. It does not attempt and is not intended to open a comprehensive path from zero to a fantastic fish only or reef tank. What it does do is give a lead to follow on the way towards a successful aquarium. No doubt extra considerations will arise on the way, and that’s as it should be, it means the planning is working. Each stage of planning needs individual consideration, and there will often be more than one decision to make. On the way, research using books and/or the internet is useful or necessary.

Where is it practical to site the aquarium?

Try to choose a location away from direct sunlight, to assist with proper lighting control. There should not be heavy and/or noisy household traffic passing (reasonable traffic is acceptable). There needs to be a reliable power supply available, ie. power outlets. Generally easy access to the aquarium is required. If floors are suspended, consider floor strength - aquariums full of seawater are heavy!

What size aquarium?

The aquarium should not stand on ordinary furniture, but on a properly designed stand. The aquarium may need a hood. These need to be taken into account. Then the available space for the aquarium can be considered.

What type of system?

The system can be fish only or reef. This decision affects other later decisions. Most will opt for a reef.

Sump or no sump?

A sump is a small aquarium that is attached to the main one. It supplies extra water capacity to the system, and allows heaters, sand beds and protein skimmers to be kept away from the display aquarium. The sump can be beside or underneath the display aquarium. A sump on any type system is highly recommended. (If a sump is to be used, the main aquarium will need to be drilled to allow plumbing to take water from the aquarium to the sump. It is then pumped back again.) Note: if a DSB (deep sand bed) or plenum (a raised DSB) is to be employed, the sand bed area should be at least 2/3rds of the base area of the main aquarium. The sand bed should be at least 4? deep. Consider the cost for the fine sand for the DSB. A DSB in the sump is highly recommended. Leave enough room for a partitioned area for the seawater return pump.

Lighting?

Is the system to be fish only or a reef? If fish only, then two marine fluorescents are sufficient. If reef then:

Hard corals.

Best lighting is halide, supplemented by actinic fluorescent tubes. T5 fluorescent tubes can be used (marine white and actinic equally mixed) but they do not penetrate the seawater as deeply.

Soft corals.

It is sufficient to use T5 fluorescent lighting (actinic and white mixed). Halide lighting can be used, however, and will not be detrimental (ensure corals exposed are light demanding varieties).

Net seawater capacity of aquarium and sump (if used)? This is easily calculated once the aquarium size and sump have been decided. This gallonage will be excessive as, when rocks and sand are added, it will decrease. Therefore, reduce the amount by 10) unwanted contaminants. Therefore the seawater mix is at its best from the start. It is highly recommended that R/O water is always used, including the first fill of the aquarium. R/O units come in different gallons per day outputs. Remember that usually the aquarium is filled completely only once. The normal routine water change amount is 10 of the day. Heaters/coolers will not be on all the time, but it is difficult to determine a guideline percentage.)

OK. The list is there and it indicates the guideline aquarium equipment cost and electrical running cost of the system. These will not be completely accurate but near enough to either dissuade the desire to have an aquarium or to go ahead. There are other costs, of course. For example, no account has been taken of the fish and/or corals that are to inhabit the aquarium. Then additional equipment, often considered later, might be obtained, such as a calcium reactor, a de-nitrator, or a canister filter etc. Maybe coarse coral sand up to 1? deep, will be used as a decoration in the display aquarium.

Nevertheless, the scaffold will have achieved its purpose, which is to generally guide the new aquarist down a path that cuts its way through what can be a confusing beginning.
