Hi Heather welcome to the forum
I moved your post so your question can get the attention it deserves.
When you're cycling with fish, you have to do daily water changes until the cycle is complete.
ammonia and nitrites are toxic to your fish.
If you didn't have fish, you wouldn't have to do water changes.
1) It's normal for the beginning of the cycle. Start 50% daily water changes. Use Prime as your water condition. This will detoxify the ammonia for 24hrs between water changes.
2) See # 1
Here's a basic explanation of the
nitrogen cycle:
First your ammonia (from fish waste and left over food) will rise.
In a few weeks you'll see the nitrite levels rise and the ammonia levels start to drop.
After a few more weeks you'll see the nitrate levels rise and the nitrite levels drop.
Ammonia and nitrites are toxic to your fish.
So until your cycle is complete, you need to keep the levels down with daily water changes.
When you having readings of 0 on both ammonia and nitrites with some nitrates showing, your cycle is done.
Good luck
