Here's a thought, why not go to your closest aquarium (not store, I mean like your city's aquarium) and ask them what they do and for pointers? Or just try contacting them. It can't hurt.
Ill refrain from giving you anymore good advice on your project becasue you've asked me, even tough you have already decided to take some of past my advice in hope of correcting the problem. The fact that any curing tank seal or seals can be compromised by a structure the tank is either sitting on or attached to when unperceived moment is involved, is something that has been well documented, all you have to do is research it on this forum. Albeit, as you wish I wont provide you anymore useful information.
all structures settle over time, and even a small movement can create huge problems down the line. What he is saying is if your tank is attached to the house, it will settle with the house, and a small movement can flex your tank structure enough to cause a leak. The floor could settle somewhat when the tank is filled, resulting in some flex therefore causing a leak... any number of things could be causing it. I am sure the house wasn't designed to handle the static load of 4300 gallons of water, plus all of the materials used in the tanks construction.

My suggestion is more fun. But requires the leak to be substantial enough that it would lose a cup of water in the space of 5-10 seconds. So you would need to measure how slowly the tank level drops to work out how much you are losing.
Fill the tank half way or more (higher level will put more pressure on the leak and make it easier to find because the water will push through it faster).
Wait a few hours for all water movement to cease.
Get some food coloring or some other dye in a bottle.
Put on some old ratty shorts and climb into the tank carefully without moving too much water around.
Move slowly across to the window and start squeezing out some of the food coloring along the window surounds. See if you can deteck the water 'moving' out through a gap anywhere.
Otherwise, contact a pool-leak detection company and ask their advice. After all, that is how a lot of pool companies detect where the leak is in the 'tub' of a pool here in sunny Australia.
Such a pity you can't see it gushing out anywhere. And such a pity you can't put atmospheric pressure into your room to see where the bubbles enter the water. haha.
Best of luck Pete. And congrats on your engagement. It isn't easy for us single men to find a partner who is so accepting of our slightly obsessive aquarium hobby.
My only concern was that you don't have a catastrophic tank failure and someone gets hurt.The seal on the window is NOT curing. It has been cured for MONTHS!!! You don't know what you're talking about.

That aside I diden't know you were recently engaged, congratulations, I truly hope the relationship last.:thm:
