How much to feed.

[fishtaco]

I just bought a bottle of Phyto Feast from Reef Nutrition and the directions on the bottle say 1-5 drops per gallon per day. This seems like a huge amount for my 15 gallon nano tanks. I was thinking maybe 5 drops every three days would be enough, in both tanks? Feeding mushrooms, cloves, zoo's, xenia, feather dusters, gsp, etc. Hopefully this is a good food for them, any ideas if this is all I need to feed or is there something else I should be feeding too. I usually throw a half cube of frozen plankton in each tank the day before my weekly water change but it seems like most is eaten by my fish.

Yeah, my xenia started pulsing more within a couple days of using this stuff and everything looks a little happier, but wow it stinks and I just don't want to make my levels go up from overfeeding.
