Frozen food by HIKARI

Have you tried their MEGA MARINE yet?

I have purchased it because HIKARI was always working
for me if we speak about fish food, but I am dissapointed
with this particular purchase. First - they look very "processed",
I have a feeling I am feeding with dried pellets soaked in water.
And when I thaw a cube in a spoon of fresh water and put
it into the fish tank most of the stuff is floating
on the surface... I was expecting the food to be
suspended in the water column - was I right or wrong?
What are your experiences in that matter?

BTW - their OCEAN PLANKTON is working as expected, this
food looks like just raw mixed plankton frozen alive.
