    Hi all,
    I just watched a program with a small snippet on bio reefs

    The idea is running a low current through a steel structure submerged in the sea.
    I'm no fundi on this, but sps corals attached to these structures are growing at anywhere between x5 to x16 times faster than normal!!
    A few articles on this

    Can we not use the same idea in our tanks?

    Cheers!

    Sorry for asking, but why the slow flow over a steel structure?
    As far as I can see from the article, they build bio rock structures & then attach broken corals to that. (Basically the same procedure used in mariculture farms)
    They usually do this in shallow lagoons with constant slow flow through the area, & have great results in this way...
    Did it look something like this?

    Sort of, the electrical current is run through the steel structure which attracts calcium etc out of the water. The steel structures over just a few days get a solid calcium covering, corals attached to this structure have been recorded as growing at incredible rates.
    Hope this makes sense

    I also watched this program earlier and wondered why they would use any form of current at all.

    Hmmm , now I get it!!! I thought you were talking about "water CURRENT", lol.
    Might actually work.
    Do they keep the current running through the steel frame the entire time it takes to grow the coral, or is it only for the initial growth stage?

    Might be a bit dangerous in our tanks. (but if it works, the results could be amazing)
    Literally growing a SPS reef in a couple weeks!

    Did they happen to mention how much Current? Voltage?

    also watched the program while trying to study :whistling: they doing it in Bali. kinda cool. wont work in RSA the cables will be stolen haha. it reminds me of using co2 in a planted tank. if by some chance it can be done in your tank i think the corals would use the supliments very very quickly so dosing would increase a lot more and the would be expensive in a large tank. but was cool to watch they have been doing it for 7years and those corals on the steel structures are huge! also have better colour

    imagine the amount of calcium that would be required just to coat the steel frame!!
    :eek:
