Thanks JZ199! I was planning on using the rock my brother had in the tank.Welcome!! And welcome back to the hobby!!
My tank was disgusting when I got it and I couldn't get it cleaned for the life of me, someone told me ORIGINAL magic erasers, and that worked like magic making my tank look brand new with minimal effort, just be careful not to scratch it, and I wouldn't use it on acrylic
And your live rock are you getting from a store that's currently in a tank, or are you putting in dry rock to make it live?
