They don't make the TEK elite 36" in a 4 bulb. If you think the tek is the best route for me then I might go ahead and get the 6 bulb. Looks like the width includes a few inches of metal (from the pictures) so maybe it won't be too bad and the back sides of the tank will benefit from the extra light. If you think this is overkill for this tank then set me straight as I don't want to waste money and additional power if not necessary. If I did go with a 6 bulb setup, what bulbs configuration should I get with the same critters and potential to dabble in soft corals later.
