Cool....there's the photos!
Thanks for the help getting those to show up. Or did they show up on their own finally?
Sadly, the hot water trick didn't work. I did hot water directly from the faucet, which comes out about 140*F and while it was filling, I had 3 pots boiling water on the stove. As the pots would boil, I'd pour them in, refill them, and put them back on the stove and repeat.
The initial sealing attempt with silicone didn't work either. Wound up breaking the right end glass, which is where the leak was, and replacing it. That gave an opportunity reseal that unresolved leak.
But after it was back together and silicone cured, it started leaking from a natural fault line in the slate. That was even more of a challenge to seal.
The hoods were also a big challenge because they'd been taken apart and one had been modified. The hoods are dual-light versions, so they have a T-8 fluorescent at the front and a dual tube bulb fixture at the rear. I put blue bulbs in the incandescant fixtures, so at night I get a nice moonlight look.
The seller was the original owner and she gave me all of it's original equipment, including the big Supreme Aquaking filter unit which hangs on the back and has a big 1/4 horse electric motor just sitting upside down, on top of a plastic box, and driving a water pump. I've put that, the original Supreme Heater back on the tank. Both still work...but I'm not going to use the filter unit.
