Well I thought I had to have it before I put the fish in so I rushed. Now that I can put it up and get them in. I will look around on the net since there is no rush.
Just curious, is there a way to 'test' the sand in like a glass or a cup to see what it will do when submerged under water and see if it will work or not? I don't mind using it if it's ok and safe...
