What's good about close loop? I've seen post about it all the time but I'm just not sure what it does and what so good about it?

a closed loop is a clean way to provide your tank with the proper water current without the need of power heads in the tank. I think the main reason people like them is because you dont see any power heads in the tank (thats why i use one). The way that i have mine setup on my tank is water is drawn into the pump from the main display then goes through a SCWD to alternate water flow back into the tank through 2 outlets.

Does it mean thtat if i have two ecoteck power heads giving me about 6000gph then i don't need close loop? Or it somthing more then that?

What does SCWD stand for?

Nope, that's it, just water flow. A LFS has an 4 way Oceans Motion hooked up to a closed loop with the OceanMotions revolutions They get some incredible flow that is constantly changing.

I got a smaller one called a Squirt on my 40g tank no revolutions though. I'm now trying to figure-out if I should go with this for my 75g or use Tunze or Vortech pumps. A lot of people with bigger tanks and closed loops have switched to these pumps.

I run a closed loop but think I will be switching to the Eco's. Because of more circulation and less power consumption. Not to mention it will be quiter in the living room. I will also have more variety of current selection. I wish some other closed looper's would chime in and see how they feel about the differences about the two choices CL or Eco's. I know there is a bit of a price difference but in the long run you will make it up in the electric bill. IMO the Eco's are a much better choice now than CL's. Technology is winning the game right now as far as I'm concerned.

You can alternate your flow and no heat from extra power heads

If you read Marc Levenson's article on Sumps he makes a good case for not having the majority of your flow come through the sump. He favors a closed loop to limit the sump flow to about 5X the tank size.
