Answer
It is most likely a construction input, such as mineral dust on the rocks you used.  You should be able to get rid of it naturally, with water changes, after a few months.  There are also a few foam removers on the market, but they only work with certain types of foam.  Foam can be caused by many things, but I am guessing that it came from construction inputs.
