Apart from this, Seachem has designed the conditioner so that it is also able to detoxify water. It goes further than removing chlorine and will clean out various harmful substances such as ammonia, nitrite, and any heavy metals in the water.

As far as the cost is concerned, this conditioner is a great budget option as the 100-milliliter bottle can treat up to 1000 gallons of tap water. It is because you only need to use one capful of the liquid for every 50 gallons of water. That being said, be sure to use it carefully as any spills or leaks can be quite an issue.

Buying Guide

Here’s a list of some things you should consider when looking for a conditioner for betta fish:

– Conditioner Form

Most common betta conditioners are available in either liquid or tablet form. While they both achieve relatively the same goal of clearing out your tank from unwanted substances, the way they work is quite different. Thus, choosing the right one for your tank setup can make a difference in its effectiveness and the amount of work you put in.

When it comes to liquids, these are often much more concentrated and thus, only need a few drops for many gallons of water. Due to this, liquid conditioners are a better choice if you can easily handle the conditioner and have a larger tank.

On the other hand, tablets are much easier to use but often clear tanks much more slowly. So, if you are a beginner or have a smaller tank, these would be more suitable for you.

– Cleaning Capability

Probably the most important thing you should consider when buying a new betta conditioner is its cleaning capability. That is because your conditioner is responsible for clearing out many harmful toxins and substances which can be fatal for your fish. So, depending on the type of water you plan on using, be sure to find one that can easily get rid of chemicals and toxic substances.

– Processing Time

Regardless of the size of your tank, you should look for a condition that can treat any quantity of water within an hour. In other words, it should be able to treat up to four to five gallons of tap water in under 15 minutes. So we recommend checking the processing time offered by different filters and investing in a fast one.


Let’s discuss a few frequently asked questions related to betta fish water conditioners:

1. Do bettas need a special water conditioner?

While not compulsory, using a special betta conditioner is very useful. That is because bettas like to stay in water between a pH of 6.5 and 7.5. So, while you can purchase special water for bettas, it is much easier to use good quality water conditioners with regular tap water. These conditioners can detoxify the water and remove various chemicals that can harm your fish.

2. Can you put too much betta water conditioner?

Yes, using too much betta water conditioner can harm your fish. That being said, using too little conditioner will also be harmful to your fish. Thus, when using any water conditioner for your betta tank, make sure you follow the instructions closely and avoid spilling or dropping it.

3. Is 7.6 PH safe for bettas?

A pH of 7.6 probably won’t kill your betta fish, but it is not suitable for their health. It is because bettas thrice in pH levels between 6.5 and 7.5. So going above, this is likely reaching the threshold of what your fish can handle.

4. Is aloe vera safe for betta fish?

Yes, aloe vera is both safe and beneficial for betta fish. It is known to be great for reducing stress in fish and also relieves their natural slime coating. It is crucial because the slime coating protects fish from harmful chemicals and diseases which may be present in water. So, using a conditioner with aloe vera is a great choice that will help your fish a lot.

5. How long does it take for betta water conditioners to work?

The exact amount of time it takes for your betta water conditioner to work will vary depending on each specific conditioner. However, a good rule of thumb you can follow is that it takes two minutes to clean the chlorine and another five minutes for other substances like chloramine. So, waiting for about 10 to 15 minutes for safety should be enough for your betta conditioner to work.

6. What nitrate level is safe for betta?

A safe nitrate level for your betta tank would be under 20ppm. Keeping levels under 20ppm ensure that your fish and plants are not harmed by nitrate, which can often be fatal if highly concentrated.

7. How often should I change my betta fish water?

Your water changes should take place once every week but should also alternate between small and large water changes. The best way to ensure that your water is clean and safe is to change one-fifth of the water weekly, and once every three weeks, change one-third of the water.
