Cheap marine snow alternative?

Well, I've made a mixture of water, vitamin powder, and plankton. When I go to work on Monday I'll feed my corals and my fiancee's some of it.

My work tank is a 13g cylinder, with the dimensions of 20" by 16". It is lit by an 80 watt 16 LUXEON LED array which I built myself. Corals include a couple mushrooms, finger leathers, micro-zoo's, and an anemone.


My fiancee's work tank is 40 gallons and has similar corals.


I'll post results in 2 weeks.
 
Well, its been 3 weeks, and I can truly say that my mixture was "decent"

Both me and my fiancee's corals **slightly** closed up after switching from snow to DIY. However, it was better than not feeding at all.
