Day 4, and the plants seems to be doing really well....no melting at all. I'm astonished, but pleased that I'm seeing new growth. I guess it'll be a while before the roots get established. Meanwhile, I'm excited that I just ordered a glass intake tube from a supplier in Germany. He posted elsewhere on this forum, and that's how I found him. From the pictures of his Fluval Edge, the intake tube almost disappears in the water, which is exactly what I want for my set-up. The perspective point for my tank is between the rocks, down the sand path, and I would rather not have the existing smokey gray intake tube be the focal point. I will post pictures once they arrive.
