Best Water for Aquarium Fish

To start a home aquarium, we must decide on what water to use for fish. Since fish are live animals, they are just like us requiring clean and ideal environment in order to stay healthy. Unlike us, the fish are much more fragile creatures. They can die fairly easy if we give them the wrong water.

Most people will agree on fish need clean water, but what is the definition of clean? Some people will think if the water look and smell clean it must be clean. The fact is that many of the chemical substances can’t be seen or even be detected by the smell. The number one fish killer in home aquariums is ammonia, followed by nitrite and chlorine / chloramine. They are all colorless, and you can’t smell them at low concentration.

Let’s get to the point.
What are the choices of water for the aquarium fish?

#1 – Tap water
In most cases, the water from your tap is the perfect choice for freshwater aquarium fish as long as you use an aquarium water conditioner with it.

Tap water is available at home to most of us, and it is the easiest and one of the cheapest sources of water you can use for home aquariums. If you are starting a freshwater aquarium, tap water will be perfectly fine unless you are absolutely certain the tap water in your area is of horrible quality.

One thing the beginner fish owners must pay attention to is that the tap water has chlorine and in some cases chloramine in it. These two substances can kill the fish and they must be neutralized before the tap water is safe to use in an aquarium. While chlorine can be easily removed by just letting the water sit for a day or two, chloramine is much more stable and you must use an aquarium water conditioner to get rid of it.

#2 – Well water
For some people who have access to well water, it is another choice for using in a home aquarium. However, one thing you must pay attention to is the water hardness. Due to the underground nature of well water, it has a lot of dissolved minerals in it which makes the water quite hard. Although most fish can adapt to a wide range of water perimeters if given time, water hardness is one of the things the fish has the hardest time to get used to. Research well on the fish species you plan to get. If they are from soft water environment, it is advised not to use well water for them.

#3 – Lake or river water
The water from a lake or a river is certainly a source of water. It seems natural to use it since there are fish in them. However, most aquarium hobbyists are against the use of such water. Not only you run the risk of having industrial pollution in the water, but there are also potential fish parasites and diseases from the wild. This source of water is not recommended.

#4 – Rain water
Some of the people might think rain water is clean when they live far away from the cities. The truth is that the pollution can affect a much larger area than you think. It is not a good or even safe source of water at all for aquarium fish.

#5 – Bottled water
If you are absolutely certain your tap water quality is horrible, the bottled drinking water is another choice. It will cost a lot more, and you will have to pay attention to the ingredient on what is in the bottled water. Some of them might not be just H2O and they can have additives which can be deadly to the fish.

#6– Reverse Osmosis (RO) water
The processes of creating RO water got rid of all the substances, which make it 100% pure H2O. You can obtain RO water by getting a RO unit. Some of the marine fish stores also sell RO water for fairly cheap prices.

RO water is pure, which means it has absolutely nothing else in it besides H2O. It can be potentially dangerous in an aquarium where the slightest change can cause the PH to crash due to there is no dissolved minerals acting as a buffer.

Important: If you decide to use RO water for a freshwater aquarium, you must add buffer back into the water before using it for aquarium. This can be done easily by using commercial available aquarium water buffer products such as SeaChem Replenish.

The advantage of using RO water is that it is truly clean with nothing harmful in it for the fish. More importantly, you can choose your own water hardness by adding different amount of water buffer. It enables you the option to create the most ideal environment for your specific fish species.

The best water for aquarium fish is tap water
While the best water of choice in term of quality and for fish health might be RO water if you are willing to take the extra cost and trouble, it does have its downside. Since you have to add buffer back into the water every time before using it, you have to make sure you rebuff the water with exactly the same hardness every time or your fish will be in shock or even die because of the sudden change.

Tap water is the most recommended aquarium water of choice for freshwater fish. It is also cheaper than RO water. The benefits from RO water is not really necessary unless you have a saltwater aquarium, or if your tap water is terribly low quality. There are other times when the use of RO is necessary in a freshwater aquarium. It is when the tap water in your area has extreme PH (too high or too low), or when the tap water is too hard, or when there is excessive amount of nitrate right out of the tap. Otherwise, the tap water and a bottle of aquarium water conditioner are good enough.

Where to put an aquarium

Everyone has to decide where to put an aquarium before setting it up. It might seem simple, but in reality there is more to it than just set up an aquarium at where you want to see your pet fish. The location of where to put a fish tank is very important for the overall health of the aquarium system. It is not just for the pet fish, but it is also for your own good too.

Top ten places where you should not put a fish tank

1. A fish tank should never be located where it can receive direct sunlight or excessive strong daylight.
All new aquarium hobbyists will run into algae problem one way or another. One of the leading causes for annoying algae growth in a fish tank is excessive lighting. Too long period of light or too strong lighting can both be the problem. Having a fish aquarium under direct sunlight is asking for an algae boom. You are also risking overheating and temperature fluctuations for the aquarium water and both can be lethal for the aquarium fish.

2. A fish aquarium should not be too close to an air conditioning or radiator.
The fish tank requires stable water temperature for the health of pet fish. Being too close to an air conditioning or a radiator can cool off or heat up the water temperature too quickly. It is very unhealthy for the fish and it can even kill them if the temperature change is too large too quickly.

3. A fish tank should not be located near a door.
Water transmits shock wave much stronger than air. If an aquarium is near a door where it is frequently opened and shut, the fish can be scared quite often. It is not good for their healthy if they are constantly scared.

4. Do not put a fish tank larger than 10 gallons on the top of a desk or on other furniture not designed for holding an aquarium.
Water is very heavy. A small 10 gallon fish tank can hold as much as over 70 pounds of water. Combined with the weight of the fish tank, equipments, gravels, it can be well over 100 pounds. It is good idea to use a strong aquarium stand instead of other furniture.

5. Do not to put an aquarium in the center of a large room.
It is the best to put an aquarium near a wall or in a corner where the floor is better supported. Unless you are absolutely sure the floor is strong enough, or if the fish tank is small and light, it should not be in the middle of a room where the walls are far away. Even the small to medium sized fish tank can be hundreds of pounds in total weight. Having the floor collapsing is not funny.

6. Do not set up a fish tank on the floor.
Even if you are fine with observing the fish in a top-down position, it is still not recommended to have the aquarium on the floor level. It is very easy for someone accidentally kick the fish tank or have something falls into it. It is also harder for water change with gravel vacuum.

7. Do not set up an aquarium too close to a TV or speakers.
The flashing of a TV screen and the loud sound from the speakers can be such a bother to the fish. Stressed fish won’t be healthy fish.

8. Do not set up an aquarium directly above an electrical outlet or power strip.
Better safe than sorry. Since aquariums hold so much water, you do not want water get too close to the electricity. Although you will need access to electricity for the filter, heater, and other aquarium electrical equipments, it is a good idea to have the fish tank set up at least a foot away from a wall outlet, and any power strip should not be on the floor level near the tank.

9. Do not set up a fish tank too far away from where you can access clean water.
Regular maintenance of a healthy aquarium requires weekly partial water change. To be close to a water tap can mean less stress on you to carry all the heavy water back and forth.

10. Do not set up an aquarium where nobody can see.
Despite the best care, accidents and unexpected can happen. You want to be the first one to notice if there is anything wrong with your precious aquarium fish. It is a good idea to set up the aquarium where you can frequently see without going there specifically for this purpose. So you can do something about it on the first sign of trouble.

Where to put an aquarium requires careful considerations in order to choose a perfect spot for both you and the pet fish to enjoy for long term. For large sized home aquariums, their locations can be relatively permanent since it is troublesome to move them around later on. Think carefully before you act!
