I'm still in the process of building the frame so I'm hoping it works out. I bought 1/4" square acrylic rods at a local plastic company and this small vice from Lowe's. I've got the main part of the frame put together. Right after taking this pic I attached the center brace. Next steps are to add small pieces that will rest on the top of the tank and hold the frame up and add the small pieces that the netting will attach to.
