ammonia test levels

I can’t figure out what’s up with this tank! It’s 10 gallons and has been set up for several months. I know it’s cycled because there was a nitrite spike a couple months ago followed by nitrate. Both are now at zero (the frogbit keeps the nitrate at zero even though my tap water has nitrate!)...

So I posted Tuesday that Sunday I did a water change and cleaned one of my filter pads and it caused my ammonia to go up. Today I did a 50% water change. PH: 7.4 Ammonia .25 down from .50 Nitrite was 0 Nitrate .05 Will do daily 50%-60% water changes till Ammonia is zero.
