Nitrate levels Axolotls

I’m having troubles getting my nitrates below 20ppm. Is this a problem? My tap runs at 10 ppm so getting it lower then that is NOT possible. It’s a 20 gallon tank with a Fluval aquaclear 110 running. My nitrites and ammonia are at 0 ppm so I know it’s already cycled as I’ve been running this system for 6 weeks. I just can’t seem to get my nitrates lower then that no matter how many water changes I do.

Your filter is cycled, so it processes ammonia to make nitrates. That's its function.

I personnally have a tap water with 25 ppm nitrates.
I start the tank with a huge amount of Egeria densa, Ceratophyllum demersum and Lemna minor (50% of the water surface) and nitrates fall down near zero within a week.

To add to/clarify the above comment, the only way to get rid of nitrates is through either water changes or getting lots of plants to eat them up.
