Bored into leaving
I was reading my BSAC Dive magazine I get each month as part of my BSAC membership, and notice an interesting article today.
Apparently low voltage currents speed up the growth of certain corals. It has been noted that some Acropora spp grow at 4 times the normal rate when subjected to low voltage. There is a long term experiment to try and prove the lab findings at the Karang Lestari Project in Northern Bali.
It has started with Dr Thomas Goreau and Professor Wolf Hilbertz creating artifical reef structures to tie nroken off pieces of coral to. Some 40 structures have been sunk and seeded to date. It works by having a net of titanium as an anode and a conductive metal (often steel from sunken boats) as the cathode. When fed with a small current a low-voltage electrical field causes the minerals in sea water to solidify aggregating into limestone; the natural building block of barrier reefs.
So, after some time spent trying to pull voltages from our tanks, it may well be we are slowing the growth of some stony corals.
Intriguing, ne c'est pas?
