what is the difference? i have used Crush Coral since i started aquarium hobby and few years ago LFS recommended me Dolomite and i have purchased 2 x 25lbs. Yesterday i was cleaning out my filter i and ran out of Crush Coral (CC) i added Dolomite.. i'm currently keeping Stingrays, Plecos, Datnoids and an Arowana.. what are the pros of either?? both raises pH and the appearance of the Dolomite are the same as CC..
Crush Coral vs Dolomite?

hello; I am not sure if there is a difference with regard to use in an aquarium as I do not use either so do not have actual experience.
That said I am fairly confident they are both very similar in basic structure which I think is largely calcium carbonate. Both are from excretions of living things often in the form of a shell.
Dolomite is a type of limestone and if I am recalling correctly is a sedimentary rock formed largely from the shells of countless sea creatures.
There may be differences in the composition of the two materials. Just guessing, but seems more likely that coral will be of a more uniform composition. Limestone should have mixed in other sediments that drift in with the animal shells.
Sorry for chiming in when I do not have the actual experience needed to give you a useful answer.
Good luck

That is the wrong substrate to use for the fish you have you should be using either sand or gravel preferably sand for the stingray. Crushed Coral or Dolomite is used primarily for Saltwater, Brackish, or some use Dolomite for African Cichlids. Some add crush coral or dolomite to increase ph level if water is soft. You actually have species that prefer lower range ph.
Both help to buffer alkalinity, by gradually neutralizing acids (fish uric etc).
If your tap water has a low buffering capacity, either will help to stabilize your tank water between water changes.
But as Tom said, rays, and arowana tend to prefer soft, more acidic waters, so I don't see the point of adding it to the tank, (especially without providing more info as to why), as to the reasoning for using them.

I add either of those to buffer my pH higher since it never get to 7.0. Always too acidic water and I know either will builder it back up to neutral water level. If water were too acidic my arowana won't eat as much. All my setups are bare bottom. I just use either material in my filter only. Thank you

Ok I apologize for not getting that the first time lol. Personally I would feel better using the Dolomite even though they would both buffer the same.
hehee not a biggy... i just ran out of CC and on the label of the dolomite it says natural product that buffer pH. i had it for at less 4-5 yrs and i used to use the CC which when i started aquarium hobby till yesterday when i ran out so i turn to this product for my sump..
