Hey I want to set up a 10 gallon nano of mostly zooathid, ricordia, hammer, star polyps... I don't want to go with any MH lighting. I was thinking of using the 20" 2x40w pc versions out there. Any suggestions. Do you think these will work well or should I consider something else?
I have read that the ideal amout of light is 3-5 watts per gallon but I don't see this rule followed very often. With this set up I will have 8 watts per gallon. Is this too much? Should I go with a sing 1x40 set up?
