Plumbing issue
Okay, so I have built a breeding system, 2 40g's, one ontop of the other. They both have a stockman standpipe, I did drill a hole, and put a piece of airline tubing in it, but nothing else..
My first tank, drops straight down, and 45's off into the tank below. The second tank, 90's down into the sump. Whats happening on both of these, is massive surges of bubbles are spitting out the bottom of the drain pipes which is causing a lot of airation on the surface of my sump and second tank. Which is also causing a ton of salt creep and evaporation. I took a video.. hopefully someone has some ideas. http://s57.beta.photobucket.com/user...da3b3.mp4.html

Sure, it's just a basic stockman standpipe.
I'm going to purchase valves today, but I already tried to limit the air intake and it didn't change anything, it actually made more of a gurgling sound when I completely stopped the airflow.

bubbles
If you give up fighting with it you could build a bubble trap........
Feed the drain into an old skimmer , kind of a bubble trap. Invert a canister over the drain line ( 2L pop bottle ) have an air vent on top... bubbles go up , pop , air goes out .. experiment with it ...

Basically there is no flow without these drain lines.. So I'm hoping to not obstruct the flow. I was thinking if popping off the 90's and putting basically a flat piece of something in it so it does slow the flow somewhat, but its causing bubbles before exiting and then it may reduce even more bubbles coming out... (Like the nets the city place along the roads that go downhill to slow the water flow).

Try putting a T fitting on the end that goes into the sump

So I picked up 4 valves to control the air intake from the overflow, and it did help a little. Bit I'm still getting a lot of bubbles.
Any other suggestions for the tank to tank, I'm going to try the T on my sump drains.
