I have this light:
it lists these properties:
• Wattage: 27 watts
• Incandescent equivalent: 125 watts
• Dimensions: 5.75" x 3.25"
• Light Output: 1,860 lumens
• Color Temperature: 6,500 Kelvin
This is all on a 6 gallon Fluval Edge. Do I have enough or do I have way too much for this tank. I keep reading that if I have too much, I am asking for an algae bloom.
