Hi, I was wondering if some member can give me some suggestions.. I am re-starting an old tank after 1 year lapse. I have a IM 24G with pumps, thermometer. I planned to use my old rock. I have bought 20lb of live sand [Nature's Ocean]. Please let me know if I can restart with the above. I was thinking if I need to reseed the aquarium with some sand/rock from another established tank. Thanks.
