Watt High Power
How is it possible for a 20 watt bulb to have enough power for high light aquatic plant?
I says on the packaging of the bulbs that it does supply enough light, but high light aquarium plants require up to 6 watts of light per gallon.
So, how are they still able to thrive?
I have a 60 gallon tank and that only comes to 1/3 of a watt per gallon.
It is a matter of how long that light is on, how far it is away from the leaves of the plant, and how much area your tank has (where the plants are planted. A 20 watt bulb burning 16 hours a day could well be enough to grow plants....trial and error at this point. Too much light and you will have an alga mess.
