Burningbaal Posted August 27, 2011 Share Posted August 27, 2011 I'm starting to plan a new custom overflow for my AGA (tempered...boo) 55 gallon. Here are the three views of what I have planned. I think everything is at the proper height. It's kind of a blend of the eshopps overflow and the bean animal. basically, I took two of the three standpipes from the bean animal overflow and put them in the outer box of the overflow. two full siphon pipes across the top should supply plenty. these are planned to all be 3/4in pvc (or flex). note the ball valve on the full siphon stand pipe, this will be adjusted so very little water (but some) goes down the non-siphon standpipe, making both silent. as the pump may fluctuate in gph, the standpipes should have room to keep up with that. if the pump goes out (for any reason), the water level in both the outer and inner boxes will drop until the siphon in the full-siphon standpipe breaks. the water will sit in both boxes at that height until the pump turns back on. the only way the full siphon in the two u-tubes might break should be if the pump is off so long that the water in the box evaporates that low...or maybe an earthquake. these will both drain into a 10gallon sump (yet to be designed) an angled photo: [ATTACH]11827[/ATTACH] view from inside the tank: [ATTACH]11828[/ATTACH] view from the top: [ATTACH]11829[/ATTACH] what do you guys think? conv_11409.bmp Link to comment Share on other sites More sharing options...
pnkrcklives Posted August 27, 2011 Share Posted August 27, 2011 I like the Idea. Why a ten gallon sump? I run a 20L under my 55 and it works out great. One chamber for skimmer/filter sock. One chamber refugium/live rock. One chamber return pump. I tried the ten gallon just did not have nearly enough room for me. Link to comment Share on other sites More sharing options...
Burningbaal Posted August 27, 2011 Author Share Posted August 27, 2011 Ten gallon for two reasons: I have one sitting around and my stand is an awkward old entertainment center (or somethng) that has shelves on the sides so there's only 24inches wide for a tank...

Burningbaal Posted August 28, 2011 Author Share Posted August 28, 2011 Any other thoughts? I want this to be as flood-proof as possible, and would appreciate as much input and improvements as I can get! Link to comment Share on other sites More sharing options...
