How to set Jebao MLW wave pump to below the minimum 30% speed?

[3836399]

I purchased a Jebao MLW-30 for my 40 gallon breeder without knowing the minimum speed on the pump is 30% (aprox 1000gph). This is still WAY too much flow and I'm out of the return period. It uses a 3 prong connector from the pump controller to the wave maker. Is there anyway to attach a resistor or something to the data wire to slow the pump down?

Or am I SOL and I just need to buy the correct size wave pump?

I think you're SOL. Just get a smaller nano one (Tunze or Sicce) and sell this one.

The thing with DC wavemakers is that they require about 30% power for the blades to overcome the resistance of the water and actually turn. If the blades are turning, then it's running at a minimum of 30%.

If you want less than that, get a smaller version. That's really the only option. Just take the pump's max output, figure out the 30% "minimum" and buy accordingly. For instance, the MLW-5 is 792gph max, so the practical minimum is 238gph.

Dremel down the blades?

Not sure how this goes on new models, old wp-40 was able to goes far below minimum lph with new adjustable power adapter, i used charger for laptop, with option to set output voltage..... So maybe u can investigate in this direction, what voltage this pump use, and try to lower it further to minimize flow.....
