Nitrates and PH

[tony1021]

How can i get my PH level up? its at 7.8 now.

already did a pwc and still kinda low

my nitrates are increasing, my water test last week showed 10ppm and did another today and showing 20 ppm.

I have been adding 2 new chemicals for the last week or so don't know if this would affect anything as their food for corals.

I've been adding zooplanktos-m daily (1 cap full) and liquid reef every other day.

other test results in case they matter:

nitrites 0 ppm
ammonia 0 ppm
calcium 450 ppm
