I'm not really a believer in live rock getting old. Regular blowing off detritus and other general maintenance should make it a non-issue.
However dead rock or dried old live rock, I for sure would acid wash before using. Mostly to remove decaying organics to lessen a cycle. The low pH of acid also unbinds any built up metals, phosphates.
If the rock was abused and has lots of hair algae on it, then follow up with bleach bath overnight to further break them down.
Im interested in using both of these methods. Do you have a short sum of instructions?
Still dont get it...., Ive read posts about destroying perfectly live rock to get rid of hair algae? Using muratic acid or bleach kills every beneficial bug (see copepods bryzoans, etc etc etc). Why even use it then? you could use any porus rock, and save yourself the trouble. The only case i can understand doing this is if you had dead rock sitting in the garage for a couple years as a precaution. Really baffles me, sures seems like you defeating the purpose of "live rock" by making it "dead" on purpose....esp when there are natural solutions to all these problems....still confused...
I'll trade you my live rock with hair algae,ect.,ect.,ect. for clean dry rock then? lol
That is a matter of personal preference, why risk having a pest that may kill coral or fish. It's a waste and pointless. The whole point of it is control. I want only what I put in my tank!
