Interesting. Thanks for posting.

Absolutely awesome . Thanks for the link .

[hans1976]

Thanks for the info...that is great news

[erickrm]

amazing.... im am going to start electro treating my tank haha

but seriously thats so crazy how it creates lime stone on the piece of metal.... very nice!

So stray voltage is a good thing? Time to throw my rio back into the sump....

[erickrm]

das wa i said lol....

that's awesome! which = faster metabolism= more consumption = less nitrates from overfeeding = better color = more growth = more coral = this is the best thing ever. but probably not practical in a home aquarium

The link wont work for me... But i hope i didnt go through all that hassel rewiring everything and throwing the grounding probe in my setup to find out i was better off getting zapped in my tank!

[erickrm]

lol no u did a good thing craig hahah.... unless you notice a decline in color and growth in your tank in the next few weeks lol..

I wonder how much current/voltage is required?

This is very interesting. While I am new to this site, and never really formally participated in the forum discussions, there are a few things that are noteworthy to the reefing community, from what I can bring in my perspective. While it seems the story has focused on the current needed to precipitate CaCo3, there is actually a great deal of electochemistry that occurs on the scaffold that is beneficial. First, like the story says, the DC current, which only needs to be weak, is precipitatig the calicium substrate needed for coral genesis. Interestingly though, Iron, as the Fe++ and Fe++ actually has an effect of reducing local PO4 levels on the surface of the metal and in the microenvironment for the nascent corals. The effect of a zero PO4 level is that the ability of Ca++ to dissolve in the water is markedly reduced. While it may seem counterintuitive, the low aqueous solubility of the Ca++ actually is conducive to coralline growth. Thus, I have experimented myself with iron bars to reduce PO4 in my 120, and it does work quite well to bring down (scrub out) PO4. So long as one can tolerate the risk of introducing additional ions other than Fe+++ and Fe++ (i.e., lead, copper, aluminum other unwanted dissolved metals) the process works nicely in the reef tank. Finally, the navy has been sinking iron ships for years to generate reefs!
