We are no further ahead on this subject but I can tell you that it is a significant issue for this build. It is probably going to take a while to find the right solution but the principles are emerging that will be critical to the success of any proposed solution.
Any system must be capable of providing a steady but prudent amount of nutrition to both fish and coral reliably with no degradation of quality in the switch from manual to an automated system.
That first principle is proving extremely challenging to find in any commercial product and I'm afraid that most DIY arrangements are far too risky and fragile to try on this tank.
I have NOT given up on my quest but I will not lower my standards or compromise the first principle in finding a workable solution.

Hi Peter,
Here is my DIY auto feeder, capable of delivering frozen and liquid food anytime and for an extended time, all off the shelf parts, controlled by my Apex and very reliable.
1. In fridge sump consisting of an open and upright 4" pvc pipe standing a bit higher than my other sumps so it won't ever overflow, located just before my return pump
2. Hole drilled from the freezer compartment to the cooler compartment to accept a pvc pipe for delivery of frozen food to the 4" pvc sump. I make my own food consisting of various other frozen foods but mostly mysis, reefroids and garlic.
3. Rotating food bin that drops frozen food into the pvc pipe for delivery
4. Small hair dryer (green in picture) that turns on for 1 minute, directed down the shoot, so food does not stick to side walls of pvc food holders.
5. Liquid food in cooler dispensed into 4" sump via peristaltic pumps. I'm using Reef Nutrition products, combining oyster and rotifeast into one bottle, the other is phytofeast. I checked with Reef Nutrition, they said one can combine products except for phytofeast due to ph.
This is the food bin made from a brute trash can lid and individual compartments comprised of sections of pvc pipe glued over drilled out holes of the same lumen size, center is cut to accept the top of the timer pictured below, note it just sits on the timer so it can be easily lifted off and cleaned if necessary:
This is the stand (turned upside down) for the food bin, made from another brute trash can lid, the pvc supports are glued down to the fridge, note the cut out on the right to allow food to drop through:
The food bin turns via a pool timer (very rugged), since the food holders are equally spaced the time it takes to dispense food is constant so it can be controlled, it sits in a hard plastic holder which I made from the plastic enclosure that came with the timer, it too is glued down to the fridge
