The first decision you must make when you buy an aquarium is whether you plan to keep freshwater fish or saltwater fish. It’s up to you whether you want to keep saltwater or freshwater, but if this is your first aquarium, then I suggest you start with a freshwater aquarium. DoggieToys.Deals

Here’s why: Saltwater tanks are more expensive and more complex. You have extra things to worry about such as the salinity of the water, water conditioning, and temperature. Because of this, freshwater fish are much easier to care for if you’re new to keeping tropical fish.

Here’s a few other things to keep in mind when buying an aquarium:

Location

When you’re deciding on a location for your aquarium, remember that it can’t be placed in direct sunlight, or anywhere else that could result in changes in temperature.

Also remember that your aquarium, when filled with water, can be very heavy. As an example, a filled 20-gallon glass tank will weight about 225 pounds. Bear this in mind when you choose on a location for your aquarium…as it will be impossible to move afterwards.

Level floor

You will need a level floor for your aquarium, as this will reduce stress on the tank and reduce the chance of any cracks forming over time due to the floor being uneven.

Electrical outlet

Make sure your new tank is located near an electrical outlet so you can plug in the heaters, lights and pumps.

Accessible

You’ll need to have easy access to your tank so you can use the heater controls and air valves. You also need to have room for a net, and room to move decorations around.

Shape

When you’re choosing the shape of your aquarium choose short, longer shapes over tall, thinner shapes. This way there will be more surface area at the top of the water, which is much better for your fish.

Size

It is best to choose an aquarium over 10 gallons. Why? Because it’s just easier to take care of a fish in a larger tank than a smaller one. Whatever aquarium you choose, it is going to, over time, have a build up of waste material. In a large tank these toxic materials have more room to be dispersed. This means the water stays cleaner for longer, and will require less cleaning than a smaller tank.

Material

Aquariums can be made from glass or acrylic. Both have there pros and cons, but I recommend beginners to start with a glass aquarium. Why? Firstly, they cost less, secondly, they don’t scratch so easily, and thirdly, they only need to be supported by the edges.

As you can see, you need to put some time and consideration into where you choose to place your aquarium. All these things will play a part in which aquarium you choose to buy.

This introduction to saltwater aquariums was designed with the beginner aquarist in mind. There are many reasons for setting up a saltwater aquarium, not least of which is its beauty. The beautiful colors of fish and coral, interesting algae, soothing sound of bubbling water and the fun involved in creating a fabulous marine world are all reasons why keeping saltwater aquariums gives people so much fun and pleasure.

For the beginner even a brief introduction to saltwater aquariums can seem a bit daunting. This is because not only are marine systems a bit complex to set up and maintain they can also be expensive. Saltwater aquariums are not for everybody and even the simplest marine tank can cause headaches. Fish keeping can be tricky and marine fish in particular take a lot of time and effort to keep healthy.

This is because marine species are far more sensitive to water quality and temperature changes so you will need to be informed about the needs of all your fish as well as the tank itself. Saltwater aquariums require patience and a degree of know-how to make it work. You will also need to make sure that you can afford to keep the tank in a healthy state.

Which saltwater aquarium you choose will depend on your aims for the tank and your personal preferences. There are many different options available in terms of the fish and animals you can keep in your tank as well as the equipment you can choose from. Some saltwater aquariums are not suited for the absolute beginner.

The first thing to decide when setting up saltwater aquariums is what kind of fish you want to keep. The next step is finding out as much about each one as you can. Not all marine species are suited to beginners so you might have to adapt your wish-list to suit your level of expertise. Never take on species that are for advanced fish keepers or you could well run into trouble.

There are two main kinds of saltwater aquariums namely 1) ‘fish only’ or 2) ‘fish only with live rock’ OR ‘reef tanks’.

The first is probably the easiest saltwater aquariums to attempt. This is because in saltwater aquariums of this nature, lighting is not really an issue and you can use a simple tank with its usual equipment and only a few extra bits like protein skimmers, powerheads and live rock or sand.

These kinds of saltwater aquariums will usually be either a community tank containing species like clownfish, damselfish, gobies, wrass, and dottybacks, or an aggressive tank where you will find species like lionfish, triggers, eels, groupers, and larger predatory species.

Before you choose your fish, make sure you know EXACTLY which species live well together to avoid your tank turning into a complete massacre. If you are a novice to saltwater aquariums start with a tank that is at least 10 gallons in size. This is because most if not all of your fish will easily outgrow the tank.

Go for the largest tanks you can afford. The bigger saltwater aquariums are easier to keep in tip-top shape.

Most important to the health of saltwater aquariums is water purification in your tank. This means that even the smallest amount of impurities in the water can hurt your fish Remember most of these animals are found in natural coral reefs where the water is very pure. So you will need to make sure that the water in your tank is clean at all times.

In small (10 gallons) saltwater aquariums you can use a Brita filter or water purifier column or you can use distilled water. These methods won’t work in bigger tanks, however. The best bet for any size tank is an RO/DI (reverse osmosis/deionization) system.

Filtration is quite complicated in saltwater aquariums but depends to a large degree on the fish species you intend to keep and how many. In a fish only tank you can use a freshwater filter for example canisters, power filters and the like. You can also try a wet-dry trickle filter. If you decide to keep a reef tank you might want to use a natural filtration system like live rock or sand or a refugium.

Protein skimming is also important in saltwater aquariums and it is strongly recommended that you do it, especially if you have lots of fish in your tank. A protein skimmer uses foaming bubbles to separate fish waste that floats up to the water column from the water’s main flow.

The foundation in your tank will require the laying down of live sand. In saltwater aquariums sand doesn’t only act as a substrate it is also the breeding ground for millions of vital bacteria. These bacteria help the nitrogen cycle to work efficiently. The sand is also home to the small animals that help control the waste products in your tank.

The best sand for saltwater aquariums is calcium carbonate (aragonite). You can get this from crushed corals, or finer sands. You can also use silica and quartz sands but they are not as good.

What about live rock? Probably one of the most expensive features of saltwater aquariums, prices may put off many a budding marine aquarist. Live rock can be bought by the pound and it is expensive because it’s the real thing. In the sea live rock makes up a reef structure with little calcium carbonate structures produced by corals. Since live rock is harvested from nature and laws govern this harvesting you can begin to understand why it is so expensive.

Live rock is important to saltwater aquariums for the bacteria it introduces into your tank. These little organisms keep your water filtered in the same way it does in nature. It also acts as a home and shelter for your fish and a place for coral to grow. It is well worth the high price you pay. ‘Fiji’ rock is a good choice if you can find it. Try to avoid any live rock that has a mantis shrimp on it as they multiply very quickly.

Let’s move on to the lighting in saltwater aquariums. In a fish only or fish and live rock tank lighting is not really an issue. In a reef tank, however, it is critical. This is because light is needed for most corals and anemones to grow. Special lights are needed for a marine tank so use one of the following:

Power Compact Fluorescent (PC)

Very High Output Fluorescent (VHO)

Metal Halide (MH)

Remember you will still need to cycle your tank and perform the necessary water quality testing before you add any of your livestock. So there you have it – the basics of what to start thinking about as you set up saltwater aquariums. We suggest doing plenty of further research to make sure you know exactly what you are doing before you get started.

Marine tanks are not for everyone, so make sure they suit you before you spend a lot of money.

Aquariums have evolved into a very popular hobby, with about millions of aquarium and tropical fish enthusiasts worldwide.

Starting in the 1850s (when the predecessor of the modern aquarium were first being developed as a novel curiosity) the ranks of aquarium keeping has grown as more sophisticated systems including lighting and filtration systems were developed to keep aquarium fish healthy.

However before you can get started in the hobby you must first buy an aquarium. When you get to the pet store or specialized aquarium store you will have lots of aquarium tanks to choose from:

Metal Framework:

Most of the old style aquariums are made with sheets of glass, which are held in a metal framework. This is usually constructed of pieces of angle iron or stainless steel, which are welded together at the corners. Leakage between the glass and metal is prevented by putty aquarium cement, acrylic or silicon sealant.

Battery Jars:

Fish Globes or Bowls: This type of aquarium is useful for emergency purpose, but is not to be recommended as a permanent features. The glasses are cast in one piece and a crack, however small, may suddenly expand and cause a flood. This not only results in a loss of fishes but also necessitates the buying of a new tank, as it is impossible to repair the old one.

Also, when looking through the walls of this type of aquarium, there is distortion, which adversely affects one’s view of the fishes. Similar disadvantages apply in fish globes or bowls.

Plastics:

With the ever-expanding applications of plastics, it is not surprising that these synthetic that these synthetic products have been used to replace glass for aquarium. Plastics have advantage of being unbreakable, but are soft enough for the surface to become scratched. This is in time will mar transparency.

Vitorlite:

This glass-like material is available in many different colours and some very pleasing effects can be obtained by applying it to the sides to back up the aquarium. Moreover, being opaque Vitorlite will hide the wall and any unsightly wires or other apparatus behind the aquarium.

Wood:

Aquarium frameworks with wood are desirable mainly for aesthetic reasons. The wooden framework however will have to be constructed from plywood to prevent warping.

The advantage of the wood lies in the fact that it can be polished, covered with upholstered rug, stained or coated with colours to harmonize with the furnishing of the room.

When starting a new aquarium it is important to understand the nitrogen cycle. Many new aquarium owners jump into the hobby of fish keeping too quickly. Before purchasing fish, the aquarium must be cycled. This could take anywhere from twenty four hours to four weeks. In an established aquarium there are certain bacteria that help the breakdown of ammonia to nitrates, but they are not present in a new tank because they are generated from existing fish. If there are no existing fish, then there are no good bacteria.

The basic principle of the nitrogen cycle is this. Fish eat food and generate waste. That waste along with excess food and plant debris become ammonia in the aquarium. Ammonia is toxic to fish and needs to be broken down. That’s why the nitrifying bacteria is important. This bacteria, turns the ammonia into nitrites which are more tolerable to fish than ammonia. Next, different nitrifying bacteria will turn the nitrites into nitrates, which are even less toxic to the fish and other aquarium life. The nitrates are collected and minimized by filters; however they will eventually accumulate in the tank. Regular water changes are required to remove the nitrates from the water.

It is important to set up and run an aquarium before any fish are introduced into the environment. Wash the tank and any substrate and decorations thoroughly with water. Don’t use any soap. Fill the tank with de-chlorinated water and attach filters and lighting. Allow the tank to cycle until the water is no longer cloudy and sufficient P.H and water temperatures have been established.

Now it is time to purchase the fish! Buy hardy fish such as danios, barb, gouramis, and live bearers. They should be able to withstand the high nitrite levels and ammonia in the new aquarium. Only introduce about four fish at a time. Float the fish in the bag in the aquarium for about fifteen minutes before adding them to the tank. This will help the fish become acclimated to the water temperature in their new home. When adding the fish, be careful not to allow the water from the bag into the aquarium. It may be contaminated, or will at the very least, throw off the temperature and P.H. Allow the fish about two hours to become acclimated before feeding.

Only feed an amount that can be consumed in the first two to five minutes. Overfeeding is a common problem in an aquarium. It is important not to overfeed, because excess food will become debris adding to the ammonia levels. This is especially important in new aquariums that lack nitrifying bacteria. Test the water P.H. every day within the first month. Watch the tank for cloudiness; if the aquarium becomes cloudy, it may be necessary to add a clarifier. Monitor the fish for signs of stress or illness. A healthy fish will be swimming regularly. Lethargic fish will usually hover near the surface of the aquarium. After about a week change approximately ten percent of the water and begin regular maintenance.
