Modified New Era Marinegrazer
 

So I tried one puck in the tank and its way too much food for my three fish. I tried cutting the puck into quarters and just dropping it in, but my conch was all over it would eventually get lost in the rock work.

So here is attempt three using a safety pin on a quarter puck, so far fairly successful.

Also my fish are all getting really fat since using this, it's awesome.
