flow for closed loop

[untamed]

Each of my CL Dart pumps pull through a single 2" intake. Suction is not an issue. As said, the key is to have a large surface area strainer.

OM 4 ways work very reliably. I dislike the look of power heads in the tank.

The way my CL is done is how it was reccomeded by the owner of Oceans Motions right down to the size of pump, I believe it's all in my build thread. Spent several hrs talking to him on the phone & got some great info.

This one?

[The Grizz]

Yep that one

And this one that shows the intake manifold but what I didn't get a pic of is the loc-lines that are attached to the returns. I put 3 - 3/4" on each return.

So what size lines are those and what size pump exactly?

Intake is a 2" line & returns are 1" so when running its a even ratio of 2 - 2. The pump is a Dolphin 3600 GPH. Loc-lines calculate out at 2 1/4" per return.

Thanks, what do you mean ratio of 2-2?
