Can You Use Spring Water in a Fish Tank?

In addition, water parameters of spring water, such as pH, hardness, water quality, etc., are also ideal for fish tanks. If you put spring water in fish tank, you can relax and know that your fish will stay healthy and active.

What Are the Benefits of Using Spring Water in Fish Tank?

Some of the benefits of using spring water in fish tank are:

– High Oxygen Content

Like humans, fishes also need a sufficient amount of oxygen to survive. Springwater has higher oxygen content than other types of water for fish tanks.

– Keeps Your Fish More Active

The molecular arrangement of hydrogen oxide in spring water is responsible for its levitational quality. Due to this, your fish feel free to swim without water pressure and will be more active in the fish tank.

– Provides Nourishment

Springwater contains many essential nutrients, minerals, and prebiotics to provide nourishment to your fish.

Type of Water for Fish Tank: Options Other Than Spring Water

As a devoted fish keeper, it’s your responsibility to ensure the health of your fish. Therefore, whatever you put into the fish tank should be checked and studied well before using. You should keep this in mind while choosing water, too, as it’s the most important medium of life for your fish in the tank.

It’s possible that sometimes you don’t have access to spring water. In such cases, you should know what other water options do you have for your fish tank.

– Tap Water

Tap water is the most commonly used water in fish tanks. It’s because you can get it easily from any tap in your home, and it doesn’t harm your fish.

However, if your fish belongs to a climate where the water aspects are very different than your tap water, then tap water isn’t suitable. You can treat the water to adjust its pH, gH, nitrates, etc. if you have no other option before putting it in the fish tank.

Another thing that you should be careful about is chemicals in tap water, especially if the water source is municipal water supply. Tap water is usually treated with different chemicals to make it safe for humans. But the chemicals used during treatment are toxic for fish, so be careful. You can use a dechlorinator or chloramine on your tap water to make it suitable for a fish tank.

– Bottled Water

Bottled water doesn’t contain many contaminants, which makes it suitable for fish tanks. However, some bottled water contains chlorine that should be removed before you add it to your aquarium. The commonly available bottled water includes:

Purified Water

If the tap water passes through the RO/DI system or is distilled before putting in bottles, it is purified water.

Filtered Water

Filtered water is also tap water that is filtered using different filters, such as charcoal, to make its taste better.

Spring Water

When the bottled water is collected from underground aquifers or springs, it’s already pure and doesn’t need any treatment to make it drinkable.

You can use bottled water in the fish tanks, but you must remember to check the water parameters first. Bottled water for fish tank can be used after treatment to make it suitable for fish.

Rain Water

Rain water has low pH and mineral index. So, it needs a little adjustment to be suitable for the fish tank. Moreover, it’s easier to collect. All you have to do is place a bowl in the rain and pour the collected water into your fish tank.

Distilled Water

Distilled water is pure water as it has been purified under strict purification standards. You can use it if you need purified water in less amount. Although affordable, you’ll need a lot to fill bigger fish tanks. If you need water for fish bowl, then distilled water can be a good choice as you won’t need much.

How Spring Water Affects Fishes in a Fish Tank?

Spring water at different locations varies in composition when you look at the minerals content and pH. Fish can adjust to the changing pH, but the fluctuating pH can kill your fish.

If you think that spring water is pure and very safe for your fish’s health, you must reconsider. The springs are polluted with waste from industries and households at different locations, especially in developed nations. These pollutants can lower the amount of the important minerals in spring water.
