PH Level: Rising PH Levels

[AirIck]

Hello, I have a newly cycled tank and completed my first water change over a week ago. I tested my parameters today and noticed my PH level rose from 8 to 8.2 to 8.5 in a span of 5 days. I use the Hanna PH 2 pt tester (red one that cost about $40). All other levels are good (except alkalinity that is high). However, I only have 2 clowns in the tank right now with live rock. I am no where close to being ready/experienced for corals.

My question: Should I be concerned my PH level is rising this fast within 5 days? Is 8.5 bad? Is there anything I can do to lower the PH level or prevent it from possibly rising to more dangerous levels? Also, I have not changed any filter media (I have a Fluval Flex 32.5) that came with Carbon in the top container and BioMax in the bottom container. I did replace the media foam with Intank Media baskets this morning as I heard the baskets were an upgrade from the styrofoam. Please advise!

pH 8.5 is OK, but may not be accurate. It is uncommon without using high pH additives.

So there is no need to be alarmed at the moment and/or change anything out of my filtration?

Correct. if not dosing high pH additives, one never needs to be concerned about pH being too high.
