To all interested: I was browsing and ran across a source for chladophora algae balls. 1-2" balls, 3 for $10. (I am not connected with this source in any way, info only) I know there was a lot of interest last week. http://members.aol.com/waterlife1/plants.html Jamie <"\\\>< Aquatic plants, water chemistry, and cichlids Greenwood, SC http://www.ais-gwd.com/~jjirons
