I have a couple of suggestions. Karl Schoeler is quite talented as an aquascape artist in his own right, and has a very good eye. He's quite well known because of his fertilizers, which were some of the very first good ones made in the U.S. The second is to talk to Jan Bastmeijer. I know he has seen a lot of Dutch tanks, he might be qualified himself. If not, I bet anything that he could get us in touch with someone qualified in the Netherlands. For someone with an Eastern perspective, why not as Claus for some suggestions. I know he has contacts in Singapore. Karen
