Common Questions
How many hours should a 10 gallon planted tank light run?
Start at 6 to 7 hours daily. Increase slowly only if plants grow well and algae stays controlled.
Can too much light cause algae?
Yes. Excess light without enough plant mass, nutrients, and CO2 is a common algae trigger.
Do low-tech plants need an expensive light?
Usually no. Hardy plants often do better with consistent moderate light than unstable high intensity.
