Hence clean your tank correctly and feed only the optimum amount of food to your betta.

Silica Content:

Generally, tap water is what is used by betta fish tank owners as water in the tank. However, tap water contains a certain level of silica which could spark the production of brown algae in betta tank. Along with that, sand or gravel is usually used as a substrate. Sand contains a pool of silica content. Therefore, even if you change your water, there is no way your substrate won’t help in the production of silica.

Lights Imbalance:

Light as a variable affecting brown algae in betta tank is a controversial topic. Brown algae, it is thought, can overtake live plants in the aquarium that depend only on sunlight to thrive when you do not provide sufficient light.

On the other hand, in extra lights, brown algae can employ photosynthesis to quadruple their food production and proliferate quicker. Hence we say moderation is the key. Install just sufficient lights in the aquarium.

Improper Ventilation:

Fish breathe out carbon dioxide and inhale oxygen and algae, much like plants do the opposite. Hence, if proper ventilation is not provided in the tank, brown algae may develop. A good water filter and the air filter are not only necessary for your betta fish’s health but a clean and hygienic habitat to avoid the growth of any brown algae.
