[ENGReef]

I aksed on my build thread, but what lights do you guys suggest using ?

Try to use as much deep red as possible, like 660 nanometer.

I have not found the lighting to make a massive difference frankly. I have not had a lot of luck with the cheap horticulture fixtures off amazon/ebay. they seem to last about a year and then conk out.
