125 lighting with t5s

[mahoneyc3]

i want to do all types of clams, and lots of them, in my new 125 tank, but i would like to only use t5s, i was thinkning of 8 bulbs of the 54 watt, would this be enough and if not how would i make it enough, i think i can only fitt 8 under the cannopy- chris

I think that would be enough. I've got a Tek 4x54w T5 on my 55g and I keep 3 croceas and a derasa with it.

thanks, but im not sure becuase the 125 is a bit deeper than the 55 and im not sure if the t5 wold give me the type of penetration i would need, any one else have sucsess with t5s and clams???
