Lighting, Too much a bad thing??

Setting up a new tank.... on a couple planted tanks Ive kept before, i purchased some nice t5 lights from aquartraders.com .... They worked really really well.... And were gorgeous lights... Now i had two 54w on a 55gal and the plants loved it, got a little alge growth, but plecos were happy and taken care of.... My new tank will not be planted, will be a basic african tang lake tank.... its 100gallons would it be ok to have the same amount of light? should I go more or less??? I dont want an alge problem, dont want to have to get snails or pleco to control it either. thoughts and suggestions much appreciated!

i ended up doin 36"x3x39w.... figured roughly watt per gallon..... hope I dont get a problem!?? Thanks for all the feedback.. lol

If you are not going to have plants the lighting is all up to you..if it will be bright or dark enough for you

if you start seeing algae growth just give the tank a 5-7 day back out to kill it all off or just simply keep your lights on less.

Or get a couple snails. I had a nasty outbreak of the orange/brown algae back in August when I had the blinds up in my room to have a fan in the window. I bought 2 mystery snails (apple snails) from petsmart and a couple weeks later it was all gone. And they haven't bred yet either! (either that or my Striped Raphael Catfish has eaten all the lil ones lol)

Edit: Durr I can't read, totally missed the part where you said you didn't want to have to get snails or a pleco. Just ignore me
