How to get rid of air in the drain flow.

So what is the best way to plumb my drain line into my sump to get rid of air? Right now I have this after setting up my fuge/sump.



I didn't want to use the media, I just put it there to break the water. At the bottom of all this I have a ton of micro bubbles. I know of sponges and sock, but I really want to do away with haveing to use theat stuff. Any ideas??

 

I see you have created a little wet/dry filter....

We extended the end of the overflow tube so that it was below the water line in the sump, this reduced the water noise, and then.... tied a filter sock to the end of the pipe to control the noise and salt spray from the bubbles created by the air in the line...

Yes this added a little extra maintenance every week, yes there are those who would recommend against such a filter, but it went a long way to quieting the tank and making it easier to live with....

 

I took those out of my W/D, but will be getting rid of them. Thought about using staggered egg crate to mke the flow change directions. I also want quiet. Maybe if I do come up with something it will be loud, we'll see. I really want to be filter free.

 

Try putting a pee trap on your drain, it should help slow the water down and wont let it fall full force onto the media. Or just another elbow for it to go around.

 

my setup is not the same. BUT.. as you go into your sump, have the water go into a Y pipe. (you can use a 20 degree off set to line it up right). the bottom part of the Y should be as deep in the water as you can ( it, close to the bottom). the other side of the Y pipe extend up. if the bottom of the Y is under water ( and it's deep enough) the air will want to travel up, so it will exit the side of the Y that you extend up. I have 2 tanks, that return flow back to my main tank and this is what I do. it stopped 95% of the bubbles. on mine, I did not go straight up, I used 2- 90 degree's then I went up to of set for space.

in Homedepot (or your store that you like) they have the pipes, there are some that really are Y pipes.. and there are some that are close. the ones (for my setup) that were close were better the top and bottom were straight, with a part comming off the side like the letter K ( minus the bottom \ ) that works better then a Y ( I just don't know the real name for it.)

 

Try cutting the inlet pipe of the overflow at a 45 deg. angle. Sounds funny I know, but this creates more surface area to let in water, like a funnell. Worked for me.

 

Thanks for the input guys. I decided to go with a Herbie overflow setup. No noise, no bubbles. I'm going to do a separate write up of what I did when I make it. Probably next weekend. I have all the parts, but I'm waiting on a gate valve I had to order on line.
