I emailed the company about that and they wouldn't give me a good answer. It's been saying that it's coming soon since I started looking at them in August '11. If you get one be sure to post if it's good or not. I ended up getting the Eheim 2232 for like $40 on CL. It's made for up to 35 gallons, but with the valves it worked perfect for my 17gal riparium. It's real nice and super easy to use.
By the way the tank looks great. What's the variegated plant in the middle? I really like how that looks.
