    Morning all
    I have a stock of Bio rock as well as some coral rock. I need to build up a base for my tank which will then have live rock on top which will then populate the sterile rock.

    My logic tells me that coral rock should be better than bio rock because it is natural and has been alive before and must surely re-populate quicker than a ceramic rock?
    What are the experts opinions?

    Thanks!

    Mhh I am no expert but I have biorock as baserock, and i just love the spaces and gaps that it allows you to make.
    How big is the coral skeletons, you could always glue them to make interesting shapes.

    As for the period of time it would take to become live again, i would hazard a guess and say the thickest media would take the longest, but dont take my word for it:)

    These pieces of coral rock are big - bigger than the bio rock, so they can also make interesting gaps

    you can see where all the creatures used to be. I think this rock should be good. Anyone know anything different?

    Hi Bayls - personally I think that it all depends on the size of your tank. If you have enough space available - use both. I think that bacteria would populate both types of rock - and yes - depending on how porious both types of rock are, how long it would take to become "live". Being base-rock, you would not really see the rock in the end - especially when covered in coralline algae.... It also depends on the size of your skimmer, DSB, whether you use an algae scrubber or not, etc, on the actual amount of live-rock you require. Some people get away with very little live rock.... Others believe that you need a LOT of live rock to assist in filtration....
    BUT, I think personally that in the end, it all depends on you what you want to achieve with your tank....

    Good luck.
