I have a "t" on mine so you should be fine. I invested in some locline so I could control my current.

There is very little that is necessary in our tanks. I think the question you should ask is if you want the alternating current in your tank. The alternating current can give your corals some additional life as they eb and flow back and forth with the currents. This is also somewhat more natural than constant flow from the same locations. I really like my SQWD on my 75. Its been going strong for about 2 years now.
