Finally finished this beast and have been repairing New2Natives 450 acrylic lately. Already dropped in a new floor! Cant wait to show you guys because i know quite a few of you have owned the tank previously and it will look familiar. I will be uploading the video of me taking the first swim in my 650 as soon as i figure that out lol, and pics are on the way too. If you dont believe me flame away until the pics are up, but anyways.....I chose Gold Label Pond and Aquarium sealer for my window and used no bolts but 2x4's to support the glass while my sealer dried. I used 11 tubes, i saved one in case of a future leak, and they ran me about $420.00. (Worth every cent this is AMAZING stuff!!!!) The tank has not leaked yet (fingers still crossed) but its been full for 5 days now and was tested be ME swimming around for the last couple of days. It was a great feeling to finally jump in and become my dream that started over 2 years ago. Tops are complete and i am working on an overhead filtration system. Sorry to tease everyone without any pictures, But i still dont have internet at home and have to sneak on good old MFK while im at work. Lots of good pics though on the way, I documented the entire window sealing process in detail during the madness. Pics soon i promise!!!!! Thank you everyone for the tips along the way,especially NolaPete, Pharoah, and SatansGoldFish for discovering the Gold Label Product!
