You can adjust Feed Mode on the Settings tab under VorTech control. Simply log into EcoSmart Live, click VorTechs in the header, then click the Settings tab on the left (in between VorTech Modes & Live Demo). Feed Mode is the first setting in the list. You can adjust the speed and duration - just make a selection and it will be saved in real-time to all of the VorTechs in the selected aquarium. If you use the ESL iPhone app, you can also visit the Settings page under VorTech control.
Regarding using Feed Mode in your daily schedule, you currently can't, however we have it on our short list of features to add to EcoSmart Live.
