Betta Fish Tank FAQs

What should the pH level be in a betta fish tank?

Bear in mind that the pH level is not similar in different kinds of water.

As usual, pet owners will choose to make use of the resource from the faucet in their household as a potential provider of water for betta fish. But is the pH level in it suitable for our betta?

Luckily, the answer is yes.

The ideal pH for betta fish is neutral 7.0 or can be slightly acidic, falling somewhere within the range of 6.8 to 7.4.

In the tap water, this figure fluctuates from 6.5 to 7.5, which is still life-sustaining.

If you are uncertain about the actual pH of your homes tap water, have it tested by extracting a water sample and bring it to the vet stores.

They will do the job for you. Or if you prefer, equip yourself with a proper pH test kit to check the water yourself.

One more thing to remember is that the pH measured at the start of the week may differ from that of the weekend due to changes in water particles, so test your tank at least 1-2 times per week.

What causes cloudy water in a betta fish tank?

Betta Fish Tank

If you have ever dealt with bacteria bloom (so-called cloudy water), you may know it is one of the most frustrating things that can happen in the fish-keeping hobby.

Cloudy water is a typical condition in an aquarium, usually occurs 2 to 4 days after fish are introduced to their home.

It doesn’t matter how many water changes you do or how often you clean the filter media; the water is still cloudy. Possible causes are:

  • Bacteria growth: When your tank is not fully cycled in terms of the nitrogen conversion, the water becomes very cloudy each time you add fish food because of the bacteria that are suspended in the water column.
  • Overfeeding: This is when you have too much food in the tank, and the fish don’t eat it. It can then sink to the bottom of the tank and later get dissolved into the water column.
  • Overpopulation: Too many fish in a restricted space tank can kick up a lot of stuff with the substrate such as debris, food waste, etc that can create cloudiness.
  • Inadequate filtration: That you are not changing the filter media often enough has an impact on the quality of the water in the way it looks mechanically. Thus, once the filter floss gets gummed up, it isn’t going to trap any additional stuff from the water. Instead, it just passes through right back into the tank.

How often should I do a water change on a betta fish tank?

It is impossible to offer an exact time of frequency for this habit as it depends on many factors, namely the size of your tank, the number of fish and other creatures there, whether it is fully cycled, and so forth.

Generally, for the unfiltered tank, changing 30-50% of the water every week is acceptable. While in a filtered one, 20% of the water each week may be enough. Smaller tanks mean more water changes needed.

But that is not all we have to consider. How about other specific cases

For a typical 5-gallon tank filled with plants and marine creatures of different breeds, if there is no sponge filter, 70 – 80% of the water should be changed every 2 to 3 days.

In case your tank is heavily stocked, more than once a week water changing should do well.

Fry tank requires more frequent water changes: from 50 to 60% of the water should be changed every other day or every few days.
