Maybe the drains are pulling down more water than your pump is putting in?
I can only tell so much from my house bud.
I guess I need to stop by and have a look when I am heading up that way???

What type of overflow do you have? Beananimal?

Is that your trickle or syphon line?

You might have something stuck in there. Mine used to get plant leaves sucked in (fw of course), and a couple times a dead fish. Open it up completely, it may flush it out.

Opened it up, and close completely, tried restarting a dozen times. Nothing's stuck other than air haha

Which is why it seems there's something in there. Can you take a pic of your overflow?

I still have the add the tubing on the secondary. So it's acting as a second emergency right now. I bought it used. And didn't notice it didn't have one.

Try taking out the elbow of the syphon line in the box, crank up the flow til the waterline in above the bulkhead, then put the elbow back on. Sounds crazy, but sometimes air can get trapped in the top of the elbow. If that doesn't work, then i don't know Those were the two solutions i used for mine. Out of curiosity, where did you get that tank? Looks like my old 135.

Hey @jeffopentax!,
Due to both drains acting as "primary drains"
I think it is drawing down more water than the pump is returning. This will result in flushing and the intake of air into the drains.
I will take a look at it when i am in the area again for him.
@LIttle Reef Keeper you need to get the system complete ( airline as discussed ) to eliminate any issues related to system "deficiencies". Then if there are still any issues or problems, it will be easier to diagnosis and resolve.

It's a 40B
Tried the elbow trick, no luck....
Thanks for the help!

Just noticed your syphon line (with the valve) has the elbow facing up. Should be facing down.

Disregard that. "Read" the picture wrong :s

The siphon line does have the valve, I think your seeing the return pipe in the pic with the 4 pipes.

I have a gate valve? that I can slowly turn. If turned one way the water drains into the sump causing these bubbles. Turn the other way I can reduce the flow and the water in the tank rises until it starts to drain from the overflow this is a separate pipe. The amount of turning of this valve is millimetres. One way bubbles the other water from the overflow pipe. Just right there is a slow trickle of the overflow pipe.

Not using the correct lingo.

But the principle is the water is drained via the down turned pipes you have at the back. Once it rises too high the upturned pipes will catch and drain the water into the sump. You must restrict the flow so that it's right at the edge I've the upturned but not using the down turned full throttle.

So what goes in to the display must drain out . Equal but opposite reaction type thing you get it?

Yep! That's what it's doing right now
But I have a ball valve, not a gate.

Ball gate whatever. You need to restrict/increase the flow to the point that there is no jet in water into the sump
