I don't want to tell you what to do- my user name has its own inferences. I have a couple 'shrooms that aren't easily target fed in the tank- so I don't.
My feed is home made- based on some internet recipes. I live on the coast so I can obtain fresh stuff pretty close to free. Fish eggs, clams, shrimp, crabs, seaweed, plankton. . . I blend it all up and freeze it. We raise a couple chickens, so I'll throw in an organic cooked yolk once in a while to get real fine particulate matter. I try not to rely too much on the land based foods- just can't be natural for the coral to eat a lot of chicken egg....or spinach for that matter- if it's all you have, try it. Spirulina is good stuff.
If I feed the tank heavily, the shrooms do tend to expand more then when the tank has less organic matter in it. I skim heavily, so am not too worried about excess food. That 'zen feeding' approach may not work for all tanks or people keeping corals.
Do build up the quantities of food- as I feel you could shock a system with too much food. IE one dropper a day for a couple days, then two, and so on, until you see some results that are what you want- not necesarily a build up of algae. Perhaps lots of 'pod (copepod, amphipod) activity- which I feel also helps feed the corals.
If I am erratic in feeding for a while, I start the cycle over- not wanting to shock the tank with too much food and end up with a nitrate nightmare. I figure the ocean has peaks and valleys in food supply, so I don't fret much about missing a feeding. I don't have a high bioload of fish, either, in any of my systems.
