Turned on new tank with two pumps and it has a pulse?

[rpkneumann]

New tank there is a pulse in the pump flow. Doesn’t matter if I run one or both pumps high or low flow rate.
Can anybody explain why this is the case?

Could the pumps be set to pulse mode vs. fixed?

A lot of pumps have a pulse mode, make sure it's not set to that if you don't want it.

I'm guessing there is a pulse mode for that pump?

Doooh - RTFM. All correct. I panicked to fast. The jabeo has actually 4 modes
Constant current
Wave
Sine
Random
Well isn’t it great what one can learn by reading instead of immediately posting?..
Thank you
