Answer 1

I'd recommend taking a water sample to your local fish store. They'll test it for free and let you know what's going on. Are you changing your water regularly? You should do 40% or so every few weeks to once a month. You should NEVER remove your gravel and clean it as you get posititve bacteria there that help your tank remain healthy.
