Shutting down the CL for a bit

[mark]

Thinking since all I've have now is some xenia, mushrooms, polyps and a Open Brain do I really need to run the CL?

Tank is 145g and the plan is to get into SPS/LPS but since I'm not there yet and I can easily do 1000gph from the sump return why run the Dart on the CL. I can also open up the sump return to push up to about 2000gph though at a lot more noise.
