I have a great piece of dry rock Id like to add back in my tank. I took this rock out about a year ago, it was covered in gha. I soaked it in peroxide and old tank water for about a month. Its been dry since. My tank has been so great lately i am hesitant to add anything cuz im scared my parameters will get thrown off. Should I culture it? Let it get to be live rock first? Or just toss it in dry? My tanks a 130 gal cube. The rocks fairly big, maybe 5-10 lbs. I have about 100 lbs in now. So idk if its even big enough to throw it all off.
