I have a question about a acapora and a montipora coral under a t5 system. I never under stood this but I understand the whole watts per gallon thing which isn't reliable but how is it if I have either coral on top of the highest life rock in my tank and only about two bulbs will hit it from a four bulb t5 aquatic life why do I need a six bulb?
