I feed frozen cubes to both my coral and to my fish. Because of my "who knows" schedule the only time I can feed regularly is about 7:30 AM. In my case a full cube is 3 times too much. Answer, I keep a "kit". This kit is a shot glass, an old drinking glass, an exacto knife, and (in my case) a 4" square sheet of 1/4 thick acrylic. The acrylic is my "cutting board". I use the exacto to carve off 1/3 of the fish food cube and sweep it off the cutting board into RODI water in the shot glass. I then carve off 1/3 cube of coral food and sweep it off the cutting board (ok you have it, it isn't rocket science) into the drinking glass of tank water. I kill the main pump, put the PM-10 into feed mode and dump the shot glass in a special spot, the fish are all ready and waiting. Then I take a large hypo and target feed the coral food to specific coral and areas of my display and frag tank. Next I drop a Algae Wafers tablet into the tank in an area that the fish expect to find it, and may add a 1-1/2" square sheet of algae paper to the plastic algae clip on the other end of a piece of string, and drop it back into the tank. After some time, I don't time it but go by gut feel, according to how the tank is responding, I flip the pump switch back on, the PM-10 knows to restart its program automatically. Sometimes I skip days, sometimes I feed 1/2 cubes. It depends on my gut feeling about tank chemistry and clarity. I feed other things at times, give my refugium a bit of phyto every couple of days or so, and have an additional dosing routine, but this is my basic day to day feeding routine. If I'm concerned I test, but generally this does nothing but reassure me because most often everything is where I expect it to be by gut feeling from experience.
I shared this little scenario so you would have something to compare to.
