Hate to say it but while it could be your tank contributing the likely cause is just Florida and the heat and humidity. Extra wet this year with associated mold, pollen etc. I've had pretty bad environmental allergies for some time and they are extra bad this year. I know plenty of people, including next door neighbor, who don't own fish tanks and are suffering pretty bad this year and my workplace sounds like a TB ward. If your running ozone that is absolutely bad especially for kids if it is not trapped at tank by carbon. I have a 200g with glass tops and it still evaporates a fair amount of water. My 32g has a net top and it probably sucks more water than the 200. I have several air cleaners in the house and use 3x at least MPR 1500/Merv 12 air filters for AC plus it has a UV sterilizer. My AC runs 72-73 which keeps the humidity 50-55%. Much more humidity than that in Florida and you're likely growing some mold. If you have a tank also evaporating a lot of water and you don't run your AC enough, you are asking for problems. I know people that turn off or crank air up to 80+ when not home during the day. Worst thing you can do in FL.
