If you don't have any corals as now you shouldn't be worry is a little high
but it don't have much effect on fish, try doing a partial change of water.
NO3 at 40ppm. is border line if the fish seemed ok you be fine as long as it don't get any higher

It should be 20ppm or, lower.

Increase frequency and amount of water changes until biofilter catches up with bioload..

Any reading over 20ppm is good sign a water change is called for.

Test frequently until params settle into wanted range.
