I have a 75 gal marieland tank and a hood with one bulb that is thin that says zoo med f318 5500k daylight. The light sits on the glass at the top of the tank.

Ihave a second hood that I could also set on top of the tank with a diffrent bulb.

I am leaving the light on for about 12 hours.
Is this going to work for my plants?

Any suggestions for me?

What kind of light Is the second light you have are these T8,10, or T5 fixtures?
