will old/bleached coral become liverock?

[gauma369]

I have an old piece of coral i bought just for kinda look of it when I first started the tank...It has beening starting to get covered in coralline algae. Was just wondering will this add with my LR already in the tank as filtration? or is just coralline growing with no big filtration help?

Yes. Live rock develops from old coral skeletons that are destroyed during hurricanes and tsunamis. Depending on the species of coral it was, it should make a rather nice piece of rock. Coral skeletons are naturally porous, so it will definitely help with filtration.

yes, you can thrown a brick in there and it will become live rock.

Yep I got a lot of old bleached coral in my tank that have worms and brittle stars living in them among other things of course

the only problem with that is your PH level from a brick. Definitely not a good idea

Don't you get essential minerals from live rock, and if that is the case wouldn't a run of the mill rock be inferior even if it became a live rock?

The problem with rocks out of your garden is the minerals that are in the rock like copper (that's a very bad one) you want to stick to what was once part of the ocean to eliminate the chance of that happening. essential minerals?? ( i don't know what you mean) Live rock is used to aid in the biological filtration.

to also add, that if you line the base of your tank with lace rock and but LR on top of it eventually the lace will become teaming with life.

I was under the impression that live rock from the ocean provided tanks with calcium, strontium, iodine and other trace elements. or is that the salt?

I had 2 large pcs of bleached dry coral and placed on in my nano with a bunch of ref rock from another local reefer, the critters and algae were more then happy to move into it. I just moved to a 29g and am using the other pc now.

moses thats the salt that supplies the trace elements
