Hi Karl,
In many areas of the open ocean, algal growth is limited by iron
availability rather than the "usual" nutrients such as nitrogen or
phosphorus. Perhaps your rebar is fertilizing the water. I would be
careful about using galvanized rebar because the zinc can be poisonous.
Perhaps a plastic would work.
