I have a strip light bulb marked as a 'F40T10 Eclipse Natural Daylight'
Right under it and along its length hairy/bushy green algae is growing on the substrate and rocks. Is this bulb causing it maybe?

My other lighting is the Coralife PowerCompacts (Lunar AqualiteTwo 65 watt 10,000K and two 65 watt True Actinic 03 Blue) and there is no algae problem under them.

See I'm using the light that came with the tank, the strip light, and the new PC's..

I dont even know what F40T10 means...

Thanks in advance.

It's a 40 watt T10 bulb. T10 is the diameter of the bulb.
How old is the bulb? They will shift their color spectrum, and lead to increased algae growth.
