Nozzle size - Richard?

The ERL pump that comes with the 2d is not rated for that much delivery. It appears you only need a little more capacity so there may be an acceptable work around. You can use a good WW pump as a priming pump for the main ERL unit and boost the capacity. I think this method will get you where you need to be, but Richard will have to confirm actual rates. In the end the best bet is to do a test with your unit and the specific WW pump you will use. Aquamist offer a triggering relay PN 806-500 for activating the WW pump with the main pump.

You can see the flow rate of the ERL pump without WW priming pump here at the bottom of the page:

There is a .3mm jet that should be around 100cc or just over if my approximations are correct that may work for your application.
