One thing worth mentioning is that the planks design it is silly easy to see how much food is dispersed onc eyou get it coded. Set up your programming, remove the plank body and set it on plate or over a napkin, and manually run the feeding program. It will disperse and you can visually see how much food was provided.
Assess it. If it looks reasonable dump it in the display or sump (to get pulled into the return pump) and watch how the fish react, how long it takes to consume, etc. Make adjustments, repeat.
Pretty simple really and the tube, pump assembly is not necessary as all you are trying to do is see how much is dispersed.
