substrate for Mbunas (yellow lalbs and aceis)

[micmacg]

Hi,

I've just put together an old world cichlid tank with 2 yellow labs and 4 aceis. I have been reading all I can find on these mbunas. I have a question about the substrate - I've read they need aragonite and so researched a product "African Cichlid Gravel" which contains aragonite,calcium, magnesium, carbonate. It's suppose to re-create the African Rift Lake environment and maintains the high pH African Cichlids need. Since the source for aragonite and calcium comes from mollusk shell would I be able to simulate this type of gravel by crunching mollusk shells into my existing gravel substrait?

yes

For other easy alternatives you can also use
Crushed coral or crushed oyster shells <-- both can be bought precrushed.
