Nice arowana.
I was looking for this type of filter. Do you have an online link where you got it from? It's not available here in Aus and would be interested to bring some in.
What is the advantage in having the filter sitting above as opposed to below the tank?
Thanks for replying Mike but wouldn't a smaller pump mean a drop in flowrate and turnover time?...Also,it wouldn't be an issue with me since my tanks are in the basement but it would appear that aesthetics would be a concern for those who display their tanks on the main floor of their homes.One of the main appeals is less head height on the pump, so you get away with a smaller pump. Ease of maintenance and less risk of flooding are also huge pluses.
