Someone here, I can't remember how long ago, pointed out that copper wire can be used to slow the growth of algae. In the trays of water and rocks I put on my orchid shelves to increase humidity, algae used to grow quite quickly. A small coil of standard copper wire in each glass tray has greatly slowed, and in most cases completely stopped, the growth of algae in my trays. I wouldn't think the ciopper would hurt your orchids-maybe you could place a coil of copper wire on the top of each pot the next time you repot?
