NAL Posted November 25, 2007 Share Posted November 25, 2007 I drilled my first hole for my overflow box (yet to be built). It's a 3/4" ID bulkhead, and I have 2 for the returns with 1/2" loc-line. I was wondering if I need bigger bulkheads for the overflow. I also need to know what size the overflow box needs to be. Here is my set-up: 20L tank 10g sump/refugium planning on a mag 9.5 AquaC remora skimmer I am planning on buying a Switching Current Water Director for the returns Link to comment
Bobalouy Posted November 25, 2007 Share Posted November 25, 2007 So you are going with 1 x 3/4" for the drain and 2 x 1/2" for your returns? I ended up using 2 x 1" drains on my 20L and I only have 780gph. I also regret not using 3/4 returns. So I would say if you want to go with one drain you would probably want to go with at least 1 x 1.25, and 2 x 3/4" returns. Or you could do 2 x 1" drains. Read through my 20L thread, and you can see all the problems I had with just 1 x 1" drain. Link to comment
NAL Posted November 25, 2007 Author Share Posted November 25, 2007 Well the return bulkheads are 3/4", they just hook up to 1/2 loc-line. So if I do a 1.25" line, will I have to run 1.25" hose (i'm doing vinyl hose) all the to the sump? Link to comment
NAL Posted November 25, 2007 Author Share Posted November 25, 2007 Read through my 20L thread, and you can see all the problems I had with just 1 x 1" drain. OK, I have read that thread before, nice tanks. I guess I will get 1 1.25" for the drain. Do you have problems with an automatic siphon on your returns? I might have missed something. I really like your tank though, good job. Link to comment
NAL Posted November 26, 2007 Author Share Posted November 26, 2007 Well I drilled the holes, I have a 1" ID bulkhead for the drain, and 2 3/4" ID returns. I am going to run a mag 5 after talking to the lady at the LFS. Link to comment
NAL Posted November 26, 2007 Author Share Posted November 26, 2007 Should put silicone around the bulkhead before I tighten the nut, or is the rubber gasket enough. Link to comment
reefone Posted November 26, 2007 Share Posted November 26, 2007 no silicone is needed for the bulkheads. dont get the mag 5 look at oceanrunner instead. Link to comment
NAL Posted November 26, 2007 Author Share Posted November 26, 2007 oceanrunner, really. HMMM OK Link to comment
reefone Posted November 26, 2007 Share Posted November 26, 2007 yes i had a mag five and it was loud and hot. u could hear the pump humming across the house. i replaced it with a oceanrunner 2500. its got a good price, low watt draw,and its quiet. alot of people use them on the other site.
