Do betta fish need a water conditioner?

Betta fish require clean water with a pH range between 6.5-7.5. You can buy specially prepared betta water, but the best water to use in a bettas aquarium is the right conditioner to neutralize any chemicals, heavy metals, or copper that may be present in the water.

Not all types of water are good for bettas.It would be better to make a distinction between what is suitable for bettas and what can cause possible health problems. 

Why do we use water conditioners in bettas tanks?

  • Ammonia harms fish such as betta by burning their gills.Fish with ammonia poisoning tend to gasp at the surface of the water. While occasional breathing of surface air is a normal part of a betta fish’s behavior,a betta with ammonia poisoning will do so in a crazier way and will show unusual swimming behavior.
  • The main reason to use water conditioners in bettas tanks is their sensitivity to poor water conditions and they can die if they don’t get pristine water conditions.
  • Ammonia and nitrite should always be kept at less than 0.5 ppm,but it is preferable to register as close to zero as possible and nitrate should be less than 20 ppm.
  • Beyond the above levels will affect bettas health and make them sick and might kill them.
  • Tap water contains harmful chemicals that kill all the beneficial bacteria in the betta aquarium.
  • Chemicals in tap water kill bacteria and prevent them from processing ammonia and this causes ammonia poisoning and serious harm to your betta fish.
  • Another hazard to your betta is phosphates.Although they do not harm your betta directly,they do encourage algae growth,which poses a massive threat to the plants and fish in the aquarium.
  • It is important to add a water conditioner in advance to make tap water safer for bettas. 
  • Water conditioners process water very quickly, but it is advisable to leave the water in the tank for 1-2 days before adding bettas.
  • Adding 6 drops per pint, 12 drops per quart, or 1/2 teaspoon per gallon of tap water instantly detoxifies chlorine,chloramines, ammonia, and heavy metals in the solid bowl or tap water.It will be safe for bettas.
