Osmolator Nano cycling every 30 seconds

[DurocShark]

Hi, I tore down my 70 gallon reef, and moved my Osmolator Nano to my 17 gallon's 10g sump. In the 70, with it's evaporative cooling fans, this Osmolator Nano would cycle once ever 5 minutes or so. But in the sump of my 17g tank, it's cycling every 30 seconds to a minute?

Both are open top, but the smaller tank doesn't have a cooling fan. While it obviously is, it's hard to imagine the level in the sump drops that fast.

I'm seeing if there's a way to adjust hysteresis on these? Tell it don't cycle so often somehow? I thought I'd ask here before contacting Tunze.

Unfortunately, their is not a hysteresis adjustment. It is something we plan to add to a future version, a bit of a delay. Is the sump a separate sump or a built in back compartment? One possibility is to move the top off hose to the main tank to delay the fill reaching the sensor resulting in an overfill which would reduce the frequency of cycling.

Thanks for your response.

Everything's in the sump right now. I'll try moving the hose to the DT.

Thanks!

EDIT: I didn't answer your other question... The sump is in the stand. This is the tank it's on: http://www.nano-reef.com/topic/365025-durocsharks-17-gallon-planar-overflow/
