Phantom sump wave.

[Byrd]

So I finally have my sump up and running on the 280g but I'm getting a phantom wave in the return section.

So a little details of the sump. Its a twin 29g tied together by a 2" pvc cross passage at the return chamber. Im running dual 1" dursos with each 29 having its own durso spilling into a 4"x12"x14"h chamber that spills into the next chamber. 1 sumps next chamber is a 12x12x13h with two 8x8x4 marinepure blocks and then it spills into a 12x12x13 return section that houses a jebao 18000. The other sump 4x12x14h spills into a 12x19x13h that will house chaeto when the time comes and then to a 12x7x13h that feeds to the jebao through the 2" pvc cross chamber.

Now the phantom wave is only in the chamber that houses the jebao and it appears and disappears on a steady cycle of waves for 20-30sec then no waves for 10-15sec. These waves are roughly 2 to 3". Has anyone ever had this problem?

heres a similar issue on a 5 sec cycle due to power supply and or controller

Jebao Return Pump cycling On/Off

So having a problem with my Jebao DCT return pump -- Its cycling on and off after 5 seconds or so. It begins to ramp up, then I see the controller flash and it turns off, then begins to ramp up again. Over and over. I've disassembled it, cleaned it with vinegar and no luck. Any ideas or...

hope you find a solution whether controller or setting perhaps thats an easy fix

Thanks for the link but my pump doesn't have a noticeable change in speeds and the controller is holding a steady setting

could your drains go full syphon, then break the syphon creating a surge in the flow down the pipes?

I thought that as well but it continues to do it even when I make sure I only get full siphon on 1 by adjusting the flow so no water makes it to the upper drain

You Don't have it in Sine wave mode do you?

If I could figure out the direction I'd answer that. The English translation is horrible

Found a PDF of manual and doesn't look like they even mention it, with mine its a long hold on feed button to enter/exit sine mode

This sounds highly likely. Or having the 2 sumps linked together is causing a back up in one of the 2 then it equalizies casuing the wayer level to surg up and down.

We have a winner, it doesn't show any indications that you are in sine mode on the controller and as you stated, it is not in the manual on how to turn it on or off.
