Tunze Osmolator

[Wd40]

I dont know why but my tunze osmolator goes on every 2 minutes and 24 seconds. Its like clock work!
Anybody knows y this is?
Its not a leak cause i turn it off at night and the water level reams even.
I thought it was my durso standpipe but my water level stays pretty constant!
I just dont know...
Any help would be nice thank you..
