As I am getting larger tanks Im draling with this problem that I havent before. Right now Im getting my 73g hex tank up for my goldfish, and when it is on the stand it is quite tall, atleast 5- 5 1/2 feet tall, and I am 5'7". I want yo use some large round rocks to aquscape it, but as I think about it I dont how to get them in. I am afraid if I stand on a chair and lean over I will lose my balance and drop them. Plus I would probably have to be on something almost as tall as the stand to reach down to the bottom. How do you do this in large tanks?
