So i have a good sized piece of live rock that I had bought for my biocube. Most of the rock fit except for a piece thats about 12 inches by 6 inches. I want to put it in my 90 gallon tanks refugium but it wont fit there either as a whole piece. If I break it up with a hammer will I cause anything to happen to it as far as hurting the tank? I dont want it to cause an issue with my parameters.
