The tank has become a little cloudy over the last week, despite frequent water changes. I suspect that the gravel may be a problem. A major gravel reduction operation is in progress at this moment. I think that a spartan, more bare glass on the bottom approach may be better. I'll post something upon completion. It's getting pretty obsessive. More tanks, species of fish, heaters, are in the works. Thanks for asking about Wasabi, Moscato, Maguey and Don Flecha (the other 2 don't have names yet).
