Ocean Rocks Ok

Guys if your looking for rocks go to your local quarry. My dad just kitted out is 8ft long Mbuna tank with natural slate. The average LFS store wanted 3pound per kilo. He must got like 15 pieces in excess of 5kilo each with the largest being over 10kg for around 30 quid from the local quarry. He said they also had lots of Granite for sale too. Do the math

Yes B & Q River Cobbles £1.00 each from the Huddersfield branch.
Stone Merchants can be cheap as well, like grayboy has said.
