Now i've read that certain species anenomes, coral etc require a certain amount of light to thrive. Now my question is, is that the gallons in the actual display tank. For instance to make things simple. If i have 130 watts on a 10 gallon tank that is 13 watts per gallon. Now what if I had that same tank, with the same lights, only i added 10 gallons for a sump(probably a 20 gallon half full).
