I just recently went out and bought 100lbs of rock to add to my 72 gallon and am wondering what is the best way to add it. I only have one fish and a sifting star "due to wanting more decor" So should I leave them in there while I due it or should I transfer them to a five gallon bucket with a heater and pump tel I am done? I also have about 2 inche's of sand bed so will that hurt the fish if it is some what stirred up?
