Thanks very much SuperDave, it's much appreciated.
As for the history of leaks on this tank. The original leak was due to me not fully nailing the back wall in. When taking the 800 apart I realized there were only two nails in the back bottom plate. Then after the reconstruction turning it into the 1500 it was all of the inside corners that needed siliconed. Solid as Sears now. But a moisture lid needs to still be made.
