Marc, Overflow Bubbles

[Bob Barnhart]

My tank has a dual bottom drilled overflow. The overflow drains into my sump
put out millions of bubbles. Is there any way to limit the amount of bubbles
that dump into the sump? I kind of thought someone's idea of a tee with one
side of the tee going to a standpipe and the other into the sump was a
thought full idea but not sure it would work with the high volume of water
flow. I'm running a GenX 8500 pump which pumps a lot of water. The sump is
my old 50 gallon tank and my tank is a 125 gallon/ 72" long.

the T with the stand pipe will work with any amount of flow as long as the
stand pipe is long enough.. To get rid of any excess bubbles, some small peices
of live rock ( maybe many small peices) around the out flow of the drain will
act as baffles. another option is to have the drain lines dump into aanother
container that sits inside the sump. as the water overflows the container, the
bubbles rise and disipate. some holes drilled into th econtainer may be
helpfull but not usually necessary.
Good Luck

You've got a few options. I like that in sump standpipe idea. The other one is
the drawing I posted a couple of days ago.

I really like to use Bubble towers. Take a narrow container like the
rubbermaid/tupperware ones designed to hold a loaf of bread. Stand it up on
end, and drill a bunch of holes near the base. Holes can be 1/2" to 1" in
size. Fill the tower with live rock rubble of various sizes, to create a wall
impeding the bubbles. Water will flow through the rock and out the holes.
Drill a hole or two in the lid, and insert your drain pipe(s).

You should only have enough rock in the tower so that all of it is submerged.
If airbubbles do escape, add more small pieces to fill some of the voids.
Keeping the lid on the tower will muffle the sounds and prevent salt spray from
getting on your sump and cabinet.

I made a bubble tower for my Model A sump (on my site). Here's a short video:

You do need a bubble trap before the return pump, to stop the few microbubbles
that do make it through the tower/skimmer.

That a good idea regarding about the breadbox with filled sand to break down
or filter out the bubble.
With cmbination of Standpipe with T and breadbox + sand will sure help fix
the sound and bubble problem in a sump.

Try a "durso" overflow! It will help quite a bit, and stop noise from the
slurping at the top of the tank as well.

These are DIY but he can make them for you if you are not the DIY type.
