I really debated about going with the 8 bulb fixture when I bought my TEK, but with the standard width on the 90 I figured that the extra bulbs on the end would be wasted as more light would spill to the outsides of the tank rather than in, especially with eurobracing.
Some days I regret not getting the 8 as it would have added just a little extra par but I am happy with the 6. The 8 bulb wouldn't work out to that much more $$, I think they are about $50 more than the 6 bulb but then I guess you can add on another $60 for the two extra bulbs.
