Hmm the list seems to be backwards?? the carib rock like sparks says is very dence and thus doesnt have as much filtration ability. also it was dry rock at one time (so more nutrients) and then dumped in the canal. Lots of algae, mantis and crabs, which is ok if you are looking for that but for most folks it leads to lots of trouble down the line. Red sea is a decent rock but usually expensive. Indo is about the best, most figi rock is porities and tends to be round boulders. Marshalls was always the best, very pourious, light and neat shapes, but the pukani has replaced that imo.
Good luck
Mike
