will my tank idea work ?

[jaydsl]

i was thinking lite penetration, as i have to upgrade to 2 250w mh for this tank and if i added a wave box
i could take it to the top
but i have heard in the past shallow is better then tall ?
and i had to get the tank , got a good deal on it
i seen the height and thought it would be cool for fish to be able to swim

if it would be fine i will fill it
