Pygmy cage substrate divider


New Member
What do you use to divide the hydroton layer from the charcoal layer from the top layer? I know Roo suggests plastic window screen, but I just cannot find any.:confused: Could one use lanscape fabric? I did get something from LLL that look like quilt backing.
I have fiberglass screening-but the concern was that it gets pointy ends that could poke a cham if it dug into the substrate enough.

Another question-how often has anyone had to re-do a tank or break one down to clean it?
