Foundation rock, as the name suggests, allows you to build a stable structure that will remain strong in high water flow and with the most boisterous fish and urchins. It is formed from pieces of ReefSaver rock, cut to give one flat stable face.
We recommend sitting on 3-4 putty feet to raise the rock slightly off the glass to allow some water to pass underneath.
Available as an 18kg box or loose from your retailer.
