Great Balls of Reef

We are trialling the use of the Reef Balls, with the intention of gradually
replacing some of the old concrete drums which have been under the water for
over 20 years. Many of these drums have either been buried under sand , or have
corroded away. One  particular benefit of the Reef Balls is that since they are
hollow and have holes cut into the balls, they should encourage marine life to
live in and around the balls.

We would be keen  to hear of any interesting marine life that is spotted
inhabiting the Reef Balls.
