10 gallon lighting question

[Thever]

I currently have a coralife 28 watt over my 10, and was wondering if there would be any benefit to going to say 3-15 watt t8's? I'm thinking of building a hood/light and saw some bulbs at lowes. Seems that 3 lamps would distribute the light a bit better in the tank.

Id also like to leave the door open for the future, possibly going w/ a 20 gallon, probably tall so I could reuse the hood.

I've heard of that being used before. Seems like those people like the effects. Personaly i use 2 cfs and 1 15w t8 for my 10gallon and that spread the light out quite nicely

Im still a bit confused regarding the actual light levels that are being attained, w 45watts of t8 light, would that be considered high light or not? From what i read, the wpg falls apart at smaller tanks, how small I dont know

anything less than a 20 long is where it gets wierd. My 10 gallon has 2 13w CFLs (not the most efficient light because of shape) and then 1 t8 at 15 w so math wise thats about 41 watts over the 10 gallon. so 4.1WPG but thats the thing that would be a very high light tank (using wpg rule). But i still cant get the HC to grow as low as i want. So to me that means i am still in the medium range. If i take into account the efficiency of my lights (cfls and t8s) i would say i am getting close to a 2.5wpg maybe less. which is medium light. So yes to CO2 and fertz
