Can this be a source of pH buffer for people that have no access to coral sand and have been looking for a more sustainable source of pH buffer other than chemically prepared or mined mineral rock material?
I'm not sure - from what is on the web page I can see, it is mostly safe stuff -
The spheres are highly porous calcareous shells of simple protozoa (foraminifers) and bring many benefits to all marine aquariums. Reef Base substrate contains natural aragonite (the most dissolvable from of calcium carbonate) that maintains natural levels of pH with its high buffering capacity. Furthermore the porosity of the spheres provides an excellent media for both aerobic (nitrifying) and anaerobic (denitrifying) biological filtration.
One will have to get hold of a bag or the distributor to determine how much, if any, sodium chloride is in there.

Sounds interesting, Kobus. I just searched for it here and found this link - http://www.marinedepot.com/Red_Sea_Success_Reef_Base_Substrate_11lb.... They are only talking about use in saltwater and marine aquariums...is there a chance that there is a bunch of sodium in it that could be harmful to the plants?
