I have heard that tap nitrates are often from fertiliser and are not so bad for the fish since it's not the biological form?

I do anything from 50-70% a week on all my tanks, with light stock as well
What is your WC per week?

Man we had more than that.coming from our well water. Put in a home filtration system with nitrate removal works great
I may be getting a wellpoint soon, I'm hoping that the water would be good for aquariums
On my old setup it was about 40% water change once weekly... plants helped a lot.
My new setup with the drip system, lighter stocking and plants should bring that number down to roughly 20% a week, although that's just a theory at the moment.

If you are afraid of the nitrate "creep" then you can just test your nitrates each week and adjust your water change schedule where it keeps your nitrates in a good place. Or, you can do smaller water changes, while testing each week, and when you start to see your nitrates get outside an acceptable range, you could then do a large 75-95% water change to bring the nitrates back down and repeat that cycle.
It's always under 20 when I test, it's just fairly expensive so I don't test every week. Better safe than sorry

Expensive to test it?

Even if you wanted to test it only once a month, you could still do what I recommend. You would just have to do a large water change on the months that you test high nitrates.
