What do people use to separate substrate from...say, decorative sand?
I am pretty sure that thousands of people have asked the same question. But what exactly are those plastic...thing (usually black)? Can I buy that online? Can someone show me some photos of how those things actually look like? I am very familiar with paper or paper-made stuff but I doubt if card board can work under water over a period of time at all.
Where should I buy that kind of "separator" ?
