so did some rearranging of the LR in my 220gal DT about 3 wks ago and did a water test today. tank has been up and running at least 6 yrs, live rock, various fish, few mushrooms. I don't seem to have any algae problems (It takes nearly 5 days for any meaningful build up on the acrylic). fish are fat and happy, snails aren't moving much even at night. I want to start adding SPS and LPS but now a bit worried. thank you for your help!!

salinity 1.026
Mg: 1400
Alk:9.1
cal: 500+
PO4: .04 mg/l
NO3: +32!!!!!

what could be causing the high NO3 and what do I do about it?
