have you ever seen anyone use this process in a commercial enclosed system?
<"Biorock, also known as Seacrete or Seament, is a trademark name used by Biorock, Inc. to refer to the substance formed by electro-accumulation of minerals ..." No; never seen, don't think this will work>
seams easy enough to add 1.5 v to the system but what are the chemicals released by the breakdown of the sacrificial steel that will be covered by the "limestone" deposits? is there better steels to use then the rebar they talk about for the ones in the ocean? Thanks again Tom Smith

Yep that would be the right biorock. The original use was to make a concrete like material for third world countries and then they noticed that it produced a increased coral growth while not producing the mineral deposits fast enough to make it worth its original design purpose. I was doing a little hunting on line and it seamed like they were able to produce
coral growth rates 3-5 times faster then that naturally seen in the area they implemented these systems and that few people have tested them in an enclosed environment. Think the limiting factor was the constant demand for calcium, magnesium and alkalinity. Could this be compensated by oversize reactors plus dosing?
<If these were indeed the limiting factors, very likely so. A good media, reactor should be able to supply alkaline earth and alkalinity in
proportion>
Have a great holiday. Tom Smith
