Diagnose what it is and what's causing it before you attempt to treat it.
How long have you had the tank set up? Last water change? Your typical water change schedule? Any leftover food? Do you take leftover food out right away?
More info will help us. My gut feeling is a spike in ammonia but you need a better test kit. You can take your water in to your LFS and they'll check it for you for free.
