anyone know how to keep from algae growing in a terrarium. I keep about 1/4" of water in the bottm of my tank and have the plants raised above it. It's not usually a problem in winter, but now that it's getting warmer, the water gets murky with algae. For the past two years, i've just cleaned it once a month or so...
Just curious if you guys have any other ideas or remedies? What do they use in swimmig pools? Chlorine?
