10 ppm isn't high--reefers used to typically operate with 2 or 3 times as much as that. Besides, it's arguable as to whether or not nitrate is even remotely toxic.

Don't worry about it.

I agree - 10 PPM is fine and not toxic. Ideally you want trace nitrate i.e. 0.5-1 ppm, however few can manage that.

Toxicity of Nitrate has been shown to some extent. The coral Pocillopora damicornis has shown reduced planulae reproduction when Nitrate levels were over 20-30 ppm and altogether stopped at anything over 30 ppm. Thus it is most definitely a stressor IMO. However levels upwards of 100 ppm are usually tolerated by fish but this will usually yield excessive algae growth.

10ppm is not bad but it cant hurt to do a water change. Or up the frequence of water changes you perform.

My nitrates do run at 0 on a Lamotte test kit but that was after adding a refugium with macros.
