What kind of water pattern is nutrient export? Is reefcrest random full on and stop?
The Nutrient Transport Mode or NTM described in Vortech can be best described in the following graph. It consists of series of pulses or waves following by high energy stream to help export the nutrients from the tank. The graph shown here is with two pumps running.

In a ReefCrest mode of a Vortech, the flows are random with pump ramps up and down but never stops. The ReedCrest mode can be best described by the front part of this graph. Jebo WP40's ELSE mode mimics this mode.

So if we can figure out a way to combine W1 and ELSE modes, we have NTM!
