What creates more algae in a fish tank?

Algae in fish tanks can grow due to a variety of reasons, including:

• Excess nutrients: Algae thrive on excess nutrients such as nitrates and phosphates in the water, which can come from overfeeding fish or inadequate filtration.

• Excess light: Algae require light for photosynthesis, so excessive or prolonged lighting can contribute to algae growth.

• Poor water circulation: Poor water circulation can create stagnant areas where algae can grow.

• Lack of maintenance: Neglecting regular water changes and tank cleaning can lead to a buildup of organic matter and nutrients that can fuel algae growth.
