Answer
Hi Randy;

Do you have a question for me?

It looks like the Nitrogen Cycle is going on schedule with nitrite being high at the three week mark. You don't need to make water changes during a fishless cycle. When we do changes with fish in the tank it's because the levels become too high for the fish and they would die otherwise. You don't have to worry about that. Let it continue on and keep providing "food" for the system. When you do eventually add fish to it, do so slowly (one inch per ten gallons) and wait a week between new fish additions for the system to "catch up". That's when you will start to make weekly water changes for the fish to stay healthy. Do them every week with a gravel vacuuming as normal aquarium maintenance. Use a good basic water conditioner and that's all you need.

Let me know what you need beyond this...
