Durso and Calfo Question

[coraline79]

I am putting in 2, 2" drains in my 125 w/ a calfo overflow. I have been researching the durso drains, and I was wondering how important it is to have the "street ell" portion of this setup? That is the 90 degree turndown that will be submerged. Since I am setting up the Calfo overflow, all the drain will be outside the tank connected to the bulkhead. I don't think there will be enough room for this, and if it were to fit then it would be connected to the interior of the bulkhead, inside the overflow.

With the limited room why not try a Hofer Gurgle Buster?

it really depends on how much flow you will have thru the drains and how quiet you want it. on the 180 gallon we just put together, it was pretty noisy without the elbows turned downward inside the calfo, but we are running about 2000gph thru two 2" drains. with the elbows, it is silent.

Subsailor-I will have to research that, but my holes aren't on the bottom, they are in the back of the tank.

Ace-do you think their will be enough room for that?

there can be :)

i made the overflow a tiny bit too small on the 180, so i had to (as my family says) "sheddize" it and use a 1.5" elbow and modify it so it would fit into the 2" bulkhead.

Oh nm i am dumb and just saw calfo

I have been running my own version of a durso but having never seen the "gurgle buster" before I think its more like that. Ive had this setup in my 40 reef for ~ 5 years now. Its as silent as a durso but can be put in a smaller overflow and you dont have to goto a specialty plumbing store to find a street el in the same size you need. Heres a quick sketch but really I think you could use one of these without an overflow box at all. There is no large hole for a fish to swim into and since there are so many holes all the way around the pipe it cant reasonably be blocked.

I talked to ace and he is going to go ahead and set it up, so I can have the ell's. They are cheap and dead silent according to him. he has them on his current 180.

Greenmako (Brian) uses some nice 'durso' type drains on his tank. Very nice and I believe pretty quiet. Maybe he can chime in on where he got them from (I have forgotten the website).

yes, but his is an external overflow drilled in the bottom - dont know how they would plumb in thru the back.

Guess I was reading his description wrong about all the drains will be on the outside of the tank.

I have a calfo, without elbows in the calfo - just horizontal holes. Then, exterior to the tank, there's a "T" turned on it's side, with a durso AND semi-rigid tubing thru the top cap of the durso. The tubing goes down past the "T", and allows air to "burp". These drains go straight down, and are noiseless.
