Common questions
How long should planted tank lights be on?
About 6-8 hours per day is a common range. Longer periods often cause algae unless CO2 and nutrients are well balanced.
Can too much light cause algae?
Yes. Strong light without enough CO2, nutrients and plant mass is one of the most common causes of algae.
