The overflow was cut from one piece 1/4" of smoke color plastic that belong to a old table top. I used a acrylic cutter from Homedepot cost $3 and a grinder for the overflow lip.
One cut piece is the width and height of the inside of the tank and the 2nd piece is the height of the tank and the length of the powerhead.
Here is the view walking into my room. I added a grapevine wood since it's the perfect size. Right now it stands out, but later when the plants grow tall, it will help complete the angle.
I still have a lot of work to do to get this tank to the way I vision it. I took pictures of my 10 gal and this 4.5 gal to see if it can compete in the AGA contest level. This 4.5 gal will not meet the AGA deadline, but will prepare for ADA 2004.
