Hello Ecotech (or anyone else who is browsing this forum and may have an answer for this question), I am having trouble figuring out how to auto tune a short pulse wave using two MP40s that are currently linked to my Reeflink and thus Ecosmart live. I basically want to be able to used the saved auto tuned short pulse with the Ecosmart Nutrient Export Mode. In the manual it states: Phase one, or the wave phase, consists of the pumps puls- ing at an expanding frequency so as to achieve a resonant wave in any aquarium at some point in the pulse cycle. If you have already tuned a wave form into your EcoSMART driver by using the auto-tune function in Short Pulse Mode, this saved resonant wave will automatically be used during phase one of the this mode. The pulsing serves to raise de- bris and detritus from the bottom of the tank and behind the rock work, where it will then be migrated out from the water column and into your overflow during phase two. What I am having trouble with though is that its appears that you can only autotune a wave for a two pump configuration (on running slave anti sync) if you disconnect the pumps from the reeflink and then asking them as master and slave. After you do that you can tune the save and save it. Unfortunately in order to get the MP40s connected back to the reeflink you have to do a factory reset so that it can detect them. In doing this it appears that you loose the wave you have just programed. Am I missing something here? Something isn't making sense to me. On a side not shouldn't you be able to autotune a wave through ecosmart live. It seems like that would be a very basic feature that should be incorporated.
