Welcome to the forum!

Any particular reason that you even need a powerhead? Is this a marine tank? Most freshwater systems don't need one... let alone an 800GPH unit.

What is the filter than came with it?

What fish are you planning on keeping?

Worked fine. Love that rock sticking up on an angle, you would swear that it is just the tip of some huge submerged rock... Did you have to glue it to the bottom or is it balanced like that?

I might be concerned about small points of pressure on the glass if the small rocks are few and the weight supported is more than just balancing ... perhaps using something with a bit of give or a more distributed bearing surface on the glass. I'd hate to see it cause a problem... some plastic wedges perhaps?
