Great Job, and thaland, that might not be a bad idea you have either. If I had thought of that before I started my build I'd probably be doing that right now. Wait I still can because I haven't added ply to the inside of the tank yet. Anyone else think that could work? Has the potential to save me a little money lol. I love this tank, and might have to try that on my future 500 gal that will be next to the 4000 gal I am building right now.
