My tank has been cycling for about 4 weeks. I have live rock and a refugium with macro algae I have done daily water quality tests and I have gone through my ammonia spike and nitrate spike. They have been at 0 and 1 respectively and my pH has been at 8.2 for 2 1/2 weeks now and there have been 5 fish in there for 2 weeks too. Yesterday I tested again still 0 and 1 but my pH jumped to 8.5ish. I feed the fish every other day, alternating flake and enriched brine.

Any ideas what may have caused the jump?

I am also using a buffer to return the pH. Should I be doing anything different?
