What Are The Downsides Of Spring Water?

While there are a lot of benefits to spring water, there are also some downsides. Before deciding to put spring water in your fish tank, you should consider the following.

The Oxygen Content Might Not Be As High

One problem with spring water is that the oxygen content might not be as high. Because spring water spends most of its time below ground, this can often mean it isn’t as oxygenated as the water above ground.

It Could Be Contaminated

Another problem with spring water is that it could be contaminated with chemicals or pollution depending on the source you’re getting it from.

It May Be Expensive

If you plan on buying bottled spring water for your tank, then it could become expensive, especially if you plan on filling a large tank.

The Water Parameters Might Not Be Right

And lastly, before adding spring water to your tank, you should also make sure that the water parameters are what you need. Oftentimes, the pH of spring water can fluctuate between 6.5-8.5 depending on the source, so checking the pH beforehand is paramount!

How To Prepare Spring Water For Your Tank

If you plan on adding fresh spring water to your tank, then here is what you should do to prepare it.

  1. The first step before anything is to boil the water. Doing this will remove any harmful bacteria that may be floating around in there.
  2. Once you’ve boiled it and let it cool, you should then test the pH. If the pH, ammonia, nitrites, and nitrates. If all the parameters are met, you can then get ready to add it to your tank.
  3. To add it to your tank, make sure that the temperature of the water matches the temperature of your fish tank.
  4. Lastly, I like to add API Stress Coat to the water before adding it to the tank. Not only is it a de-chlorinator, but it also reduces stress in fish and improves their slime coat as well!

Do You Need To Dechlorinate Spring Water?

Whether you need to dechlorinate spring water or not depends entirely on its source. If you know that it’s come straight from the ground, then it won’t contain chlorine; therefore, it won’t need dechlorinating.

What Other Types Of Water Can You Use?

If you’re not set on using spring water in your tank, then, fortunately, there’s a whole range of different water you can use for your fish as well!

Tap Water

Of course, the go-to choice is tap water. It’s the quickest and most inexpensive choice of all. Just make sure that before you add tap water to your tank that you’re dechlorinating it first.

Filtered Water

If you already have filtered water in your house, then this is going to be a great choice for your fish tank as well! And it’s also going to have the added benefit of not needing to be dechlorinated too!

What Water Is Best Avoided In Fish Tanks?

There is also a lot of water that you’ll definitely want to avoid adding to your tank as well! This includes:

Distilled Water

Distilled water is one type that you’re definitely going to want to avoid. When water is distilled, all of the minerals and nutrients are completely stripped from it. This means that your fish won’t have the essential nutrients they need to survive.

RO Water

You should also carefully consider RO water before you add it to your tank. While it’s not bad for the tank, it will definitely need to be remineralized before being added to the tank.

Rain Water

While you can consider using rain water, it’s important to note once again that generally, the pH and mineral content in rainwater is low as well due to the evaporation process that occurs.
