I feed DT's phyto three times a week for my Crocea clam, gorgonias, and to keep my pod population high. I feed DT's oyster eggs also, twice a week, mainly for my SPS
corals. Phyto is good for soft coral, clams, and some filter feeders like feather dusters, gorgonias, etc. It also, theoretically, increases the amount of pods
, leading to more natural food sources for some corals and fish. Zooplankton is mainly for SPS
corals, and maybe some LPS
. Many plankton products sold contain particles that are simply to big for corals to capture. Many of them are snake oil IMO
. Beware of what your getting.
