reefgeek84 Posted October 23, 2006 Share Posted October 23, 2006 Alright, my new tank has two overflow boxes...I am only going to need one of them for the drain into the sump...Well actually through the skimmer into the sump... I am planning on running a dart for the CL, how big does the drain that goes into the inlet need to be for that pump? Quote Link to comment Share on other sites More sharing options...
nu2reef-n Posted October 23, 2006 Share Posted October 23, 2006 The dart has a 2" MPT intake. It's always best to use two bulkheads for the intake to the closed loop pump, so you don't suck an unsuspecting fish into it. Plus you don't want to starve the pump.

Guest Mbeef61 Posted October 23, 2006 Share Posted October 23, 2006 i have two 1.5 inch bulkheads with high flow screens for my dart...just go 2-1.5 into a 2 inch T Quote Link to comment Share on other sites More sharing options...
reefgeek84 Posted October 23, 2006 Author Share Posted October 23, 2006 i have two 1.5 inch bulkheads with high flow screens for my dart...just go 2-1.5 into a 2 inch T How about a "y" instead of a "t"? Quote Link to comment Share on other sites More sharing options...
inkto Posted October 23, 2006 Share Posted October 23, 2006 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...

fly guy Posted October 23, 2006 Share Posted October 23, 2006 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.

R2R2 Posted October 23, 2006 Share Posted October 23, 2006 Hey Geek, is the bulkhead open to the tank or behind an overflow? Just wondering based on your post about only using 1 overflow. R2 Quote Link to comment Share on other sites More sharing options...
reefgeek84 Posted October 23, 2006 Author Share Posted October 23, 2006 it is behind the over flow...I would really like to utilize that drain (already has a bulk head) and will keep stuff out of the tank... Quote Link to comment Share on other sites More sharing options...
WAVES Posted October 23, 2006 Share Posted October 23, 2006 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. Quote Link to comment Share on other sites More sharing options...

R2R2 Posted October 23, 2006 Share Posted October 23, 2006 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.
