Hi bigbass,you could use marble,I don’t know what it costs but its calcium make up is suited to marine aquariums.

Taking shell grit, coral rubble isn’t allowed worse luck, not sure who sells what for how much either in relation to coral rubble.

Hopefully some one else has a better idea.

Crushed coral is always going to be expensive to buy. I used coral sand in my tank - it was a lot cheaper - $60 for a 20kg bag from Age of Aquariums. For a tank the size of yours you could go a mixture of crushed coral and coral sand to cut the costs a bit

thanx guys looks like im spending the cash butthanx for your input
