Being that it's set up inside the house, I would wait at least 3 days until I tested filled it. I'd personally take the tank outside to test fill, especially since you have wood floors. Good luck
I agree with the "take outside to try" unless you are very confident in your tank resealing skills. If you don't take it outside, I would personally wait at least 7 days if the product said to wait 3, but that also depends on the weather. If it is really humid, I might even wait longer. Some would probably call me overly cautious, but that's me.
If it isn't too late for you to make a change, GE1 isn't what you should be using. It is not an adhesive, it is a sealant. GE make another silicone product that is an adhesive and it is what the manufacturers use on new tanks. It is called Momentive. I am getting ready to build a 700 and have been doing a lot of research. Check it out.
RTV103 Black for the side seams and RTV108 clear for the bottom and eurobracing. Grainger has the best price I have found so far. I haven't found a lot of sources for it.
