So I'm upgrading the size of my tank, and since I'm doubling the size of the tank, I'm going to have to add alot more sand to cover the bottom.
In my tank right now, I bought play sand from Home Depot, and rinsed it and rinsed it and rinsed it and rinsed it and it came out PERFECT!!! I get comment after comment about how good the sand looks in the tank, so I wanna stick with the same sand.

Here's my concern:
When I rinsed the sand the first time, I was using tap water from a hose, obviously, and when I added it to the tank, there was nothing in it, it was all before the cycle and everything took place. Will rinsing, and adding sand to an established tank cause any sort of problems? I'm doubling the size of my tank, so I'll roughly be doubling the amount of sand in the tank right now as well, I just don't wanna do it before I know the facts. Thanks so much for you help guys and gals!
