| Scott the one thing that I think makes a strong arguement for this system is the particle size and the high flow energy used. the lower Ph in oth the dsb and the plenum will allow for the melting of argonite (also bacterial acids play a strong role). with a larger particle sizes migration of elements would seem to be better. In relating that to his setup I would say the constant water changing keeps his levels at the normal ocean concintration and then the small amounts of of carbonate and calcium from the plenum wold bump it a bit. I dont think this would apply to what we are trying to do in our tanks, but we could say that if we can maintain our levels with an outside source (calreactor/ kalk/additves) it would help in the process.
