T5 8 bulb or 6 bulb fixture

[quote=Nebthet;574709]A Sunlight Supply Tek 6x54w fixture will do you perfectly for your size of tank. I would say an 8 bulb fixture is better suited for tank 24 inches wide.QUOTE]

I experimented with a tek 6 bulb fixture but sold it after a couple of weeks and went back to MH/VHO's.

I would have kept the t5 unit if it had been an 8 bulb fixture.
my tank is only 18" front to back and it was more about getting a decent spectrum while still having some good par that killed the 6 bulber for me.

You just have so many more options with an 8 bulb for a very small price difference.
