So I currently have 2 tanks. A 36 gallon bow front with a typical fluorescent light and a 150 gallon with LED strip light. My 150 gallon has virtually no algae growth on the decorative rocks and caves. The 36 has substantial brown and green algae growth that I clean every month. Is the decreased algae growth due to the depth of the tank or the LED vs fluorescent? Or I guess a combination of both.
