Quic-Crete in ponds?
 

A couple of years ago I made a base for a water lily spitter out of
quick-crete but I heard that you shouldn't put quik-crete in a pond.
What is the difinitive, once and for all answer to this question. I
say where someone was making an underwater light with quickcrete and
no one questioned.

P.S. How do you spell quikcrete?
