How to Remove Chlorine From Water for Fish Tank

Are you planning to erect a fish tank and rear fish right in your backyard? Of course, the first thing you will think about is where to get water. Fish can’t live without water, so there is no way out here. Nonetheless, issues may arise from the need to fill your fish tank with water, with chlorine contained in your tap water being the primary issue.

In this post, we talk about how to remove chlorine from water for the fish tank. Removing chlorine from a fish tank can be done in some ways without necessarily the use of chemicals. Using special filters, boiling the water, letting it sit for a day and utilizing UV sterilizers are just but a few of the viable options available.

How to Remove Chlorine from Water Naturally

There are a variety of methods that can be utilized to remove chlorine from the fish tank naturally. Without much ado, let’s talk about each method in details.

  • Boiling the Fish Tank Water

Perhaps, this is the easiest way to remove chlorine from your fish tank naturally. Besides, it is not only easy to execute it but also it is effective and will cost you a negligible amount of money.

Just boil the fish tank water for about 20 minutes and it will be chlorine-free. The boiling heat and aeration created from the boiling exercise are enough to dechlorinate your water. Moreover, boiling has an added advantage. It also removes chloramine for your fish tank water.

Although you might need to boil a few gallons of water depending on your fish tank capacity, you can rest assured that it is safe and fast. Let it cool down before putting your fish in, otherwise, you might end up with fish stew!

  • Let it Sit

This is yet another simple way to remove chlorine from your fish tank water. However, the question is, how long should you leave the water to sit for proper dechlorination? Well, the answer to this question is generally dependent on how much water you need to dechlorinate, how much chlorine is present in the water, and how much exposure to sunlight it gets.

If you are using tap water, then it needs to sit in the open for approximately 2 hours so that all the chlorine dissipates. But if you are using a wider container then you can leave it for about 20 hours as there will be a wider surface of exposure.

  • Use Ultraviolet Light

Using the UV sterilizer is another natural way to dechlorinate your fish tank water.  The UV sterilizer works by bombarding water with the UV rays thereby treating your water and killing not only the chlorine but chloramine in the water. Keep in mind that chloramine won’t be removed by just letting the water sit in the sun.

  • Use Carbon Filters or Reverse Osmosis Filter

A carbon filter with activated carbon can be a great deal when it comes to the dechlorinating of fish tank water. The activated carbon effectively removes chlorine and chloramine among other compounds from your fish tank water.

Reverse osmosis filter is another method that works great. However, it has to be installed by a plumber directly in your water pipes. The downside of this method of dechlorinating fish tank water is that it is expensive and generates a lot of wastewater.

  • Use Vitamin C Treatment

You can dechlorinate water in your fish tank by use of Vitamin C. When Vitamin C is used for water treatment purpose like this one, it comes in the form of ascorbic acid. You just put one teaspoon of the ascorbic acid to each gallon of water you intend to put in your fish tank. It will quickly dissolve to neutralize both chloramine and chlorine within a short time.

Keep in mind that if you put your fish in normal water that contains chlorine and (or) chloramine, it is going to be in trouble. Therefore, always remember to dechlorinate your tap water by using the methods we have discussed above before allowing fish in.
