Hi, new to SPS. just found my SPS has shown different color spread. On the side where expose to light the most, the color looks pale where the shade area looks fine. It is still growing but just wondering if something happened.

PH 8-8.2
KH ~8.2-8.6
CA 410-430
Mag 1450

NO3 ~1
PO4 0.02
Thank you

Try to get par readings if you can, and also how long have you had it in that spot?

Your nitrates are way too low. Should get them up to about 15. SPS need some Nitrate and it will keep the Dinoflagelates away.
