best type of over flow

[NYreefNoob]

ok as a new project start's got a 37g column http://www.elmersaquarium.com/h109_37gal_column.htm

love this tank 20x18x26. nice size nano. anyways my question is how would you do the overflow, for most effeciant and quietness is biggest concern. it is tempered bottom

 

[mikey3165]

maybe you could drill the back walls high up and not make the overflow the height of the tank on a small one

 

[mikey3165]

only a small one*

Either an external overflow-completely outside the tank, or an external durso. Have just the elbow of the bulkhead on the inside of the tank. If so, you could make an overflow box to just cover the elbow. (see ellebelle's 40 breeder thread)

anyone > i know of several ways to do it and hate to have a overflow box in tank, so if i can get around that, and really dont want to cut the top of tank to make a external overflow

I think BC's idea of only the elbow being in the tank is gonna work best for you if you don;t want to do the external. Unless you make the external by cutting the notches at the top of the tank but not the very top but I heard its very time consuming.

yea...1" elbow inthe tank and thats it...alot cleaner and leaves u more room....maybe find a black elbow or paint it with krylon fusion..
