Betta fish need well-filtered water, or if you don’t have a filter then it needs regular water changes, which is where betta water conditioners come in. There is quite a bit of misinformation out there about betta fish. While many websites and pet stores may say that betta fish require minimal upkeep, to keep bettas as healthy as they can be this isn’t actually the case.

If your betta fish tank is very small and doesn’t have a filter, then it will need regular water changes to keep the betta happy. Bettas also need a minimum of a 2.5 gallon tank to be in rude health, and even with a filter the water needs changing on a regular basis. Read our article on can betta fish live in a bowl? for more information on what tank you should be keeping your betta in.

When you do a water change you need to be careful as tap water contains dangerous chemicals such as chlorine and ammonia which are deadly to fish. Thankfully there is an easy way to remove these dangerous substances from the water.

Water conditioners work to rid tap water of these dangerous chemicals, and make the water safe for your betta and other fish. There are many different water conditioners on the market, so hopefully this article helps you choose the best water conditioner for you and your betta.

Methods of Using Betta Water Conditioner 

Using Betta Water Conditioner

Water conditioner removes and neutralizes the dangerous chemicals present in tap water, making it safe to use in your tank. 

While distilled water can be used, it doesn’t contain the minerals which are beneficial to your betta which many water conditioners have.

No matter if you are setting up your new tank or just undergoing a regular water change, any time you put water into your tank you should add a water conditioner to the water you put it to ensure the safety of your fish.

Most water conditioners recommend using half a teaspoon, or 2.5ml per gallon of water, but keep an eye on the instructions and ensure to stick with the guidelines as laid out by the manufacturer.

You only want to be changing a maximum of 25% of the water in your tank at once. This is to keep the beneficial bacteria in the tank ecosystem alive through the water change, and to keep your fish from going into shock with the new water. Beneficial bacteria is very important in the tank ecosystem; don’t underestimate it!!

If you have a bowl or a very small tank with no filtration system, then you want to be doing these 25% water changes once per week, with a full water change about once a month. 

As larger tanks will have a filtration system and work with bacteria to maintain the tank ecosystem they don’t really require a full water change, unless the tank truly requires it.

When you change the water in your tank you want the new water to be the same temperature as the old water. Use a thermometer to check, and you can use a heater if the water is too cold. If the water is too hot then leave it to cool for a time.

When it comes to putting the new water in, it is better to take the betta out of the tank first. Betta fish like slow moving water, so being buffeted by a lot of new water coming in can stress them. Keep them in a tub which is filled with the old water while you add the new stuff, and allow the water in the tank to calm down before you then add the betta back into its tank.

If you are cleaning the tank, remember to only use the tank water to clean the ornaments and filter media. Do not use soap, as soap is notoriously hard to get rid of and any residue can be very harmful to your betta.

How Much Water Conditioner Should You Use For Betta Fish?

There will be set instructions for each water conditioner you buy. Different companies may make their water conditioner to suit different tanks, or have different concentrations of chemicals which have different requirements.

As a standard general rule though, you will be wanting to use around eight drops of water conditioner per pint of water, which equates to 16 drops per quart, or half a teaspoon per gallon.

As we have said though, always follow the guidelines as laid out by the manufacturers for the final instructions.

Conclusion 

Changing the water in your aquarium is a crucial part of keeping your tank clean and healthy. Equally important in keeping your tank clean is to use an aquarium vacuum cleaner to clean the substrate and remove debris. You can also look into installing a UV sterilizer which kills bacteria and viruses which could cause disease.

Water conditioner works to rid tap water of the dangerous chemicals which can otherwise seriously harm or kill your betta fish. You should use a betta water conditioner every time you add new water into the tank.

You should be changing the water at least once a week. Any less than this and you are opening up your betta to risk of infection. A betta water conditioner helps to make the water change quick and easy, while ensuring the safety and health of your fish.
