Isn't it great when kids help. lol
It would help everyone if you would fill in your aquarium info found under My Settings at the top left.
That way members don't have to ask a bunch of questions before helping.
Yikes on your ammonia, are there fish in the tank?
Did you replace your filter? Unfortunatly, you've probably lost quite a bit of benefical bacteria by rinsing and then replacing the filter media.
If there are fish in the tank, I'd suggest upping your water changes to 50% daily as long as your
pH is the same from tap to tank.
If there's a big difference you can do 2 25% changes.
Good luck!
