Hi, I am going to be moving my tank soon. It we not be a long distance at all, so would be back up relatively short amount of time. I will be wrapping all my live rock in wet newspaper to preserve as much bacteria as possible. I have about 60lbs. of live sand in a 75 gal. that I am getting rid of. I do have fish in the tank as well. I am wondering if I need to buy a product like BioSpira or something to make up for the bacteria loss from taking out the sand. Also, if I add dry sand when I set back up can that cause my tank to cycle again even though I am using my original live rock from said tank? Or should I go bare bottom and slowly add sand? If you guys reccommend a bacteria what is the best bacteria additive? Thank you so very much for any help!
