Duckyfromoz already gave you some great advice on the air cells. I just wanted to add that I seriously doubt your relative humidity is really 99% (although I suppose it's possible). I would be more inclined to think something is wrong with your new hygrometer. They are notoriously inaccurate, even the expensive ones. I would calibrate it. You can find the instructions for doing that online or in the incubating section. I would be more inclined to believe your original one that said 50% is more accurate. I just checked one website really fast and it said the relative humidity in Naples, FL is currently 59%. Granted, the humidity in the incubator may be different, but you can use that as a very loose guide.
I can't believe you are really at 99% unless you have quite a large water surface area inside the incubator. In your environment, you may very well be able to do dry incubations, just adding water for hatch. Again though, the most important thing to monitor is air cell size and weight. The more you incubate, the easier it is to tell if you are on target or not. First, find out for sure what your correct relative humidity is. Second, empty the incubator of water if the air cells are not getting large enough. Third, if they are significantly too small, also spray the eggs daily as Katharina suggests. Good luck!
