Every week water must be added to your fish tank, because of evaporation. A few tips can help your tank be happy and healthy. To have successful replenishing of the tank water you need to know the type of water, type of fish, and how to get the type of water.

Many fish such as Cory cats and neon tetras can only live in a certain range of hard water. Hard water is water with more minerals and can harm some fish. There is a solution that can be purchased to clean the water if it is hard, but is best used only when first filling your aquarium for the first time.

Before you regularly change your tank's water they type of fish your own should be assessed. If you have a variety of fish that cannot live in hard water it is best if you fill your tank with just soft water. Having a little bit of soft water can be good for the fish. Fill the tank with a fifth of hard water and the rest soft.

Soft water and hard water come from different places. Soft water comes from most bottled water, and also from tap or filtered water. Hard water is most water from your faucet. Hard water is also from your hose or outside faucet. If you need hard water to be soft, there are solutions that you can buy to make it safe for all fish. I would suggest using the solution only for the first time you fill the tank.

Some fish can only live in soft water and some fish need a certain amount of hard water. If you have water that is too hard it can harm or even kill the fish. Some fish such as puffer fish can handle little to no hard water. Also some fish such as many cichlids need about a third of hard water. If both types of fish that have crashing water types are in the same tank, another tank may need to be used to separate these types of fish.

Being able to tell the type of water that you fill your rank with can highly impact owning a fish tank. Also finding the type of fish that can live in different types of water can help you avoid death. Filling your tank regularly can help your fish live a healthy and happy life.
