Tuxido urchin - suppliments?

[Heychanelle]

Hello

I have a tuxido urchin, it seems to be doing really well but I can't find any info on care other than the basics. Do I need to suppliment with anything such as calcium, trace elements etc? (Last water test calcium was 500).
Even though it seems perfectly healthy I always worry about it (I'm always convinced something's going to go wrong with my tank ). Also do you recommend any brands for suppliments?

Thanks advance,Heres a pic

Just don’t let nitrate levels get high and keep good water conditions. No special supplements are needed
