How often do you change betta fish water?

Water should be changed at 25% every two to four weeks in bettas tank.There is no need to take out the fish while changing the water.

Be sure to stir the gravel or use a gravel siphon cleaner while changing the water.

When adding water back to the tank, use tetra aquaSafe to eliminate chlorine and chloramines.

What kind of water parameters do bettas require in their aquarium?

Betta fish need mild water with a pH of 6.8-7.5 in their aquarium. They may appear to tolerate lower temperatures, but they become sluggish and susceptible to illness in such low temperatures.

So keeping the temperature between 76 ° and 85 ° F for their overall health is best for them.They prefer soft water that can withstand a wide range of GH from 5 to 20 DH or 70 to 300 ppm.

Keep in mind very hard water can be dangerous to them. Mixing Indian-almond leaves, alder cones, RO or distilled water reduces the hardness of the water.

Take a pH level test approximately 24 hours before introducing your bettas to their new home. The pH can range from 0 (most acidic) to 14 (most basic), with 7 being neutral. An aquarium for betta fish is best between 6.5 and neutral, but try to avoid any sharp fluctuations in pH.

Water changes are essential maintenance for any aquarist. There is no filter to deal with all the accumulated waste. And you always need to add new water to replace the water that evaporates over time. Bettas love when you clean their aquarium because they like clean water and clean aquariums to survive.

Just remove the amount recommended based on aquarium setup. The water left in the aquarium contains beneficial bacteria that are essential for a healthy environment.

Why is it important to change betta aquarium water?

It is important to change the water for your fish regularly because even if the water in their aquarium looks clear, there are still particles of food and waste in it. Not only does this cause physical buildup, but the waste is converted into chemicals such as nitrates and phosphates.

What will happen if the water is not changed in bettas aquarium? 

If the aquarium water is not replaced very often then, the nitrate levels go up, the pH and KH go down, which creates a situation called the old tank syndrome, where the pH sinks so low that the biofilter stops working properly and strong or hardy fish are only about survival, but newly bought fish die off within hours or days of being added.

Can  we keep betta fish in tap water?

Tap water is the easiest and most popular choice for fighting fish.Tap water can be used if properly prepared.

Betta fish survive in water with a neutral pH around 7.0. In most cases, the pH of tap water is in the range of 6.5 to 7.5.

The smaller the tank, the more water needs to be replaced and If bettas live in a filtered aquarium, you only need to change about 20% of the water every week.
