Low Cost Indoor Pond

Step 3 Initial Construction

I built the frame slightly smaller than 4', actually 3'10", to leave room to mitre cut the 4' facing boards. I then added 5 support beams 8" from the bottom to support the raised plywood bottom. I had a few boards left, so I added a few extra braces where I thought they would help. Then I nailed down the plywood to the bottom braces. I wished I had a chalkline.
