Search reefcentral for the best answer on this, I think Ron Shimek , Eric Borneman, or Randy holmes-farley have answered this before. I forget which though.

There is a very involved nasty chemical process that must take place to remove it, only worth it on HUUUUUGE show tanks, like hundreds of gallons....IMO
