Welcome to the forum

I think the powerhead is much too strong. I know for what I would use a powerhead for in a tank that size, I would use something rated at about 200 GPH.

I'm sure someone will be by to give you an "appropriate" filtration recommendation.

The extra 6 inches in width provides a 50% larger footprint. Spend the extra money on the wider tank - worst thing is to get a smaller tank and wish you had gotten the bigger one.
