overflow type drain help
 

Picked up a 120 with an external overflow, whats the best and the quietest drain to go with

I've never had either but the consensus seems to be a herbie or bean animal
Both dead silent with the bean Animal being set and forget and the herbie needs some adjusting once in a while. I've seen both and they are silent. My durso is not.
Herbie needs 2 holes bean animal needs 3

I use the Herbie overflow and ya it's dead silent

How many holes does the overflow come with?

That is kind of the limiting factor :)

FWIW, I run a durso and it's dead silent. Depends on what kind of flow you put through it

it has 2 holes in the overflow

so i take it its gonna be herbie

herbie is my preferred method super easy to plumb , dead silent , I also have starfish in my overflow so its nice and easy to keep the water level high when I turn my pumps off to feed .

overflow
 

usually when you have 2 holes in the overflow,and i'm assuming the holes are in the bottom of the tank,one is for the return and one is for the drain.in that case i would use a stockman

both holes are for drain as i have 2 return lines on back wall
