high Phosphates and nitrates

[KiddoReefer]

I ran some test on my tank my goniopora i got from a reef show about a month ago has not been to happy not been opening it opens once here and there but not for long my tank parameters are as followed
nitrates=12.1
Phosphates=0.40 ppm
temp=79
ph=7.89
alk=7.5
cal=435
mag=1218
both my alk and ph where at 8 but because my tanks is now set up with a auto water changer i have to switch my salt that has higher leaves just trying to see if the nitrates and phosphates are something i should worry about and if so what I should do I have changes my feeding to less because i was feeding alot now that i seen videos of other people feeding there tank for how much live stock i have

The nitrate isn't high. As for phosphate, gfo or macro algae can fix that.
