The moving bed filter is something I made out of a little bottle thing. Inside I have it about half full of cut up straw with an airstone moving the water through them. Holes in the bottom and top of the device to let water in and out, with a sponge blocking the bottom holes to act as an extra filter. If you look on my YouTube channel my newest video shows it.

I have not tested the tap water but I will when I get home.

The moving bed filters purpose is a bio filter to help with ammonia. I did it more because I was interested in in that stuff more than actually needing it.

I've not the scientific understanding to be certain, but this filter may be causing the issue. The straw may be feeding things.

As I mentioned previously, with sufficient live plants (as you say you have) there absolutely cannot be ammonia or nitrite. It just can't happen, unless it is coming in from somewhere.

Aside from that, any biological filtration is immediately working against the plants, competing so to speak. Biological filtration should never be "encouraged" in planted tanks. The plants are nature's biological filters, let them do their job.

At least the Prime is saving them. But I would disonnect this and see if the nitrite dissappears within the week. Remember that even with Prime detoxifying it, it still shows as "nitrite" in tests.

So the only real thing you can do to remove the nitrite is going to be water changes.

Yes. Prime detoxifies nitrite but Prime is only effective for 36-48 hours. The detoxified nitrite still shows as "nitrite" in tests.

Byron, my tap water is reading out at over 40ppm sometimes over 80ppm of Nitrate. I called the water department to find out their readings are between 4ppm to 6.8ppm max. The guy said it was probably in my plumbing system.

Any suggestions?

Yes. Which test kit are you using? If it is the API, are you aware that Regent #2 should be shaken for 2 minutes before adding the 8 drops? The instructions say 30 seconds, but this frequently gives a false (and much higher) result. If you weren't before, try this and see what you get.

Second, I can't see how the plumbing would affect this. Nitrate for our purposes is caused by organics. People on well water can have high nitrates due to seepage from agricultural things like farming (plants release nitrate into the soil if they have excess) and livestock. But I can't see this coming from plumbing.
