I actually saw that tank when I was in Cleveland in April. He's not using nearly that much phytoplankton. And as an aside, I really thought his tank was full of green water around the clock, when in fact most of the time is it nice and clear like our tanks. I took some pictures that day, but haven't had time to post them.
Phytoplankton is definitely part of the food chain and benefits the pod population in our tank, and some corals and of course clams benefit from it as well. Some hobbyists use it all the time, some even in massive quantities. I've found that my system really doesn't seem to need it, so I use it very sparingly. Then again, my system is pretty big, I feed heavily, and the tank is mature.
