Top Fin South Seas Marine Rock
This is excellent rock to add to an African cichlid tank and it will naturally raise ph levels

I bought the smaller rocks for my 10 gallon tank. I bought two of them to kind of stack together to make a swim through. They are very natural and quite heavy so they won't move around. Make sure to rinse them very good though because some of the white residue will come off. Buy some, you won't be disappointed.
