Has anyone used Coral Frenzy Pellets?

Hey guys! I was just wondering if anyone has used Coral Frenzy coral pellets? They were cheap so I ordered a tub of the 0.5mm pellets after reading some reviews. I opted to go for the 0.5mm rather than the 1mm because I have some really tiny Button Polyps growing and I can always feed the larger ones more than one.

The corals I have are:

Green Goniopora, Red Aussie Acan, Aussie Hammer, Button Polyps, and Kenya Tree Coral (obviously the tree coral isn't eating the pellets)

Thanks!
