Nitrate levels are a very tank specific thing. I've had some tanks that suck the stuff up so fast that 30ppm was nothing. Others will go full bloom with algae at 10ppm. In general, levels between 5.0 and 7.5 are safe.
Most importantly is maintaining a good balance in your nutrients. You don't want too much Nitrate v. Phosphate or too little Potassium v. the previous. It'll take some playing around and time to get a good feel for your tank. Once you do things will really start looking good.
