What’s a Water Conditioner for Aquariums?

A water conditioner is a substance either in liquid or solid form that improves the condition of the water in an aquarium.

Tap water is treated by governmental agencies to protect us, the humans, from all sorts of bacterias, viruses, and other harmful elements. They do so by adding specific chemicals such as chlorine, ammonia, and others.

Tap water might contain heavy metals residues like lead and copper.

For your fish, such chemicals and metal residues are poisonous. For you to eliminate the risk of such chemicals and heavy metals, you need to use water conditioners for aquariums. Doing so will neutralize those elements keeping your fish safe, healthy, and happy.

How Does Water Conditioner for Aquariums Work?

A water conditioner is composed of specific chemical compounds. Once released into tap water, they initiate a reduction process.

The process breaks the bonds between chlorine and nitrogen atoms. Resulting in chlorine and heavy metals reduction.

Types of Water Conditioners for Aquariums

There are various types of water conditioners that tackle different things. Let’s view the mainstream ones.

Dechlorinators

This is the most common water conditioner for aquariums. Once added, it immediately removes chlorine.

It doesn’t act on ammonia and heavy metals though, which makes it a limited weapon in your arsenal.

Chloramine Neutralizer

Tap water contains both chlorine and ammonia When both combine they form chloramine, a toxic metal which fatal to fish.

Chloramine neutralizers are used as water conditioners. They remove chlorine, neutralize both ammonia and Chloramine, and increase ph levels within the aquarium.

Some Chloramine neutralizers can deal with heavy metals.

Complete Conditioners

As the title implies such water conditioners handle the majority of toxic elements in any aquarium.

This type is preferred for large aquariums. It removes chlorine, neutralizes ammonia and chloramine. And on top of that it increases pH levels, deals with heavy metals, and protects the vital fish slime coat.

When and How to Add Water Conditioner for Aquariums

The water conditioner for aquariums is mainly used for freshwater tanks.

Every time there’s a need to top off or do a complete water change of the aquarium, you should add a water conditioner.

The instructions to follow when adding water conditioners for aquariums may vary according to the manufacturer.

The needed water conditioner droplets, number of caps, or tablespoons all depend on the aquarium size and number of gallons used. The instructions should provide you with the proper dosage.

Always add the water conditioner to the tap water in a separate container prior to filling the tank. Or you can remove the fish to a temporary container, add the tap water along with the water conditioner then return the fish to the original filled tank.

Make sure that the water conditioner is fully dissolved prior to having the fish settle in.

If it’s a new tank, follow the instructions and add a daily dosage of water conditioners until the tank is neutralized.

For tanks with size less than 20 gallons only a couple of drops of water conditioner will do. You might opt to use a syringe or a sort of eye dropper to control the droplets.

Benefits of Using Water Conditioner for Aquariums

Once you begin to use water conditioners, you’ll notice the benefits they provide. The following are just a few:

  • Very easy to use.
  • You can use the available tap water, no need for an alternative water source
  • Economical as the value per gallon is low
  • Strong capability of eliminating ammonia and chloramine from the water
  • Promotes a healthy natural slime coat
  • Prolongs the lives of your fish by keeping tank water in good condition
  • Won’t impact the pH level in your aquarium negatively
  • Some support beneficial bacteria in the water
  • Low to zero maintenance

Tips for Using Water Conditioners for Aquariums

You can’t be careful enough when dealing with fish in tanks as they’re very sensitive to changes in the water’s chemical compounds.

To avoid such sudden changes in chemical compounds, don’t make the fish exposed directly to the water conditioners formula. Allow a couple of hours for the formula to work on the tap water and be fully stabilized prior to introducing the fish again.

Preferably, if the water conditioner comes with a dosage cap, use it. The overuse of some conditioners can be damaging to the health of your fish.

Some water conditioners are designed for specific fish type. Reading the attached pamphlet is crucial to make sure it’s safe for your fish.

Another thing you need to do is a regular check of the tank’s water. You always need to know the levels of pH, nitrates, nitrites, and other relevant parameters.

Most of the water conditioners are compatible with tank’s filtration systems.  However, some specialty conditioners may cause issues. So refer to the instructions to avoid them.

A good water conditioner formula should provide necessary electrolytes to the tank’s water. This will stimulate the health of the tank dwellers.

An extra plus is that water conditioners can be used to care for live or aquatic plants as well.

Also note that If stored properly away from direct sunlight, in a cool dry place, water conditioners can last for a long time.

Bearing in mind all the above tips, you can benefit from the fact that most of the brands can be used interchangeably. The fish won’t be affected by the change.
