Drain inlet for CL pump?

It doesn't really matter IMO... it's going to be flooded in any case so there are no serious issues of restricting the flow... Here is my dart plumbing for reference..

whoops, that was actually rev 1 :) I ended up doing a straight T from the drains to the pump...

Everything said here so far is good advice Brandon.

 

Also, you are fine reducing that darts intake side to 1 1/2" either at teh pump or up the line somewhere............wont matter........but like said, it is best to have TWO 1 1/2" minimum bulkheads feeding it......................Where do you get the "Y"'s you mention???

 

My dad had a couple of 1 1/2" Y's laying around his shop and i stole them.....actually more like robbed them becasue he was yelling at me to bring them back as i ran out the door....haha....but i dont know where to get any more.

you dont want to use the overflow box for a CL intake IMO if thats what your intending on doing. you will have a much higher likly hood of getting microbubbles after going over the spillway. also, how many teeth are in your overflow box? a "hole" in the teeth 1/8" wide by 1" tall can only handle 35 gallons an hour. IE, usually on a standard 4 inch overflow box your maxed out at like 1000-1400 gph.

 

its an acrylic tank,,, drill it for the CL intake. Or come see my new tank and see my design which incoorperates the CL intake in the overflow, but they are seperate.

Here is a better way to put it,... you can't use the overflow for your closed loop intake. OK, now,... drill a new hole or holes, buy new bulkheads depending on flow rate target, get your high flow screens to keep from sucking up fish and corals, and you are set. R2
