Without any system regulating the water for your betta in the tank, it is only a matter of time before they eventually lose their lives.

Not all water is good for the betta. It would be best to differentiate between what is right for betta and what can cause possible health issues.

Buyer’s Guide: What is a Water Conditioner?

A water conditioner removes chlorine, chloramine, heavy metals, ammonia, nitrites, nitrates, and other impurities from the water to make it safe and healthy for aquatic fishes.

Typical water conditioners vary from the ones specially formulated for the betta. The ones for betta are more diluted and targeted at neutralizing all impurities that can cause poor health or death to the fish.

The Role of Water Conditioner

A water conditioner performs the following roles.

1) It Neutralizes Chlorine and Chloramine

Chloramine has replaced the use of chlorine in many places for treating tap water. The problem with chloramine is that it dwells longer in water and not easy to take it out.

The use of chloramine is terrible for the health of your betta. It can burn or cause damage to it. Chloramine consists of chlorine and ammonia, making it a high-risk danger factor for your fish.

Putting your tap water directly into your fish tank can hurt the fishes in the long term. You can use a betta formulated water conditioner to remove chloramine. Note that not all water conditioners can effectively remove it, do your research before purchasing.

2) It Detoxifies Nitrate, Nitrite, and Ammonia

These three compounds (nitrate, nitrite, and ammonia) can harm and kill your betta. You can remove these toxic compounds by frequently changing your water and growing beneficial bacteria.

The effectiveness of those two solutions depends on the nitrogen compounds present. If they are in high quantities, such methods may not prove useful for maintaining a strong health status for your fish.

When you do a large-scale water change, it takes some time for the fish to adjust. You can add water conditioners to the water to completely detoxify nitrite, nitrate, and ammonia present in the water to a harmless form.

3) It Detoxify Phosphate and Heavy Metals

The presence of heavy metals in the tank poses a health hazard to your betta. These heavy metals come from tap water. Some of the typical heavy metals that find their way into the fish tank are copper, mercury, and lead.

Apart from arriving from the tap water source, corrosion in old pipes carrying water into the tank also draws them into the tank.

Phosphates are another hazard for your betta. While they do not cause direct damage to your betta, they encourage the growth of algae which poses a massive threat to the aquarium’s ecosystem (plants and fishes).

Removing both phosphates and hard metals is essential for a thriving aquarium. Water conditioners help detoxify phosphate and heavy metals, rendering them ineffective in the water.

4) It Promotes A Healthy Slime Coat

Water conditioners contribute massively to the restoration or fortification of slime coat in fishes. A healthy slime coat is vital for fishes to develop and heal from illness and injuries.

It protects fishes from infections from viruses, bacteria, parasites, and fungi.

5) Buffer Water pH

Some water conditioners perform the vital role of buffering the water pH in the tank. An increased water pH can cause stress, damage and potentially kill betta. You can use these water conditioners to limit the fluctuations of the tank’s water pH.

Final Thoughts

Water conditioners are essential for your fish tanks. Even if you purify the water yourself, you cannot be 100% sure that the water in your tank will remain unadulterated. Any water conditioner is effective for keeping bettas safe from toxic compounds such as chloramines and heavy metals.
