This is the funniest anti-forum. So strangely opposite the rest of the site. What if one were to aquascape with green spot aglae on glass. Like use a glass razor to crave intricate designs into the algae and make a bground pattern with it? Like art? I might try. The front and sides of my tank are clear but the back of my tank is entirely covered, so are the filter tubes but I like that cause now you can't see the filter tubes, their camouflaged against the same color. Thoughts on carving in flat algae?
I love it! If you have access, you could print your design, tape it to the glass and back-light it so you could see where to carve.
