i hope this works long term on a large scale. thanx for sharing this

how long until Jason rigs up some kind of submerged low voltage tin-can coral propogator in his lion tank?

 

Wouldn't somebody on RC have tried this if it really spurred growth? I can see those defective Koralia's that leak voltage now being sold as a premium.

It's a good premise - adding electricity lowers the energy required to create aragonite, allowing the corals to use less energy than they would have before in building an amount of skeleton. More energy to reproduce and grow out more.

 

I wonder how long it'll be before they have to build a new structure since the electricity will only work for some distance from the structure.

Good explination, I was baffeled at first. I guess electricty is being used (very loose association here) as some what of a non organic enzyme

yep. just lowering the activation energy required to join the ions in the presence of seawater. Pretty cool application.

I was actually doing a research paper on this.

 

I'm trying to find the emails I had between Tom and I but basicly he told me due to the chemical reactions such as creation of chlorine. It's hard to monitor these things in a regular marine aquarium. He suggested Lime Water (calcium hydroxide) works great. I'll look for that email but here are some links I found on it.

Conceived by coral expert Tom Goreau of the United States and German

architecture professor Wolf Hilbertz, the project began four years ago

and has already achieved remarkable results.

Just a note that I found looking through those links - be careful to make sure the information in them is correct. I didn't find major issues with the technique, but the 3rd biorock.net site lists the products of the electrolysis as "limestone and brucite (CaCO3)" - which is incorrect. Limestone is a rock made of the mineral calcite (CaCO3), while brucite is a mineral with the formula Mg(OH)2.

 

Do you have any journal articles on the technique? I'd be interested in reading up on coral growth rates/effective distance from the structure using this technique.

Fascinating!
