I'm a one year old newbe, and when I first setup my tank I was advised to put small white stone under the AS to save cash. I still have about 2 inches of AS in my 50 G tank.

The thing is that over time the cheap small white stones have crept to the surface.

As its just a cosmetic thing and I don't feel like starting again, and I know I can not just topup with AS. But could I place the new AS in another tank for a month and then use it to cover over?

Decided to bite the bullet and start over by starting a new tank project 120cm x 45 x 45.
