Hello everyone, I'm setting up a 110 gal. tank for 4 or 5 Fancy Goldfish and tonight while I was in Wal-mart garden center I saw some River Rock in 25 lb. bags the same color of the gravel I was planning on getting for the tank and was wondering if I could us this stuff instead of the higher priced gravel? I know I will have to wash it really good and maybe use a weak bleach and water solution to help clean the rocks before I use them in the tank. Any thoughts on this? Looking for feedback as I will be setting this tank up next week. Thanks, Dale
