PH LOW?

[ReeferDad93]

Using 2 test kits (Red Sea and API) my PH measured between 7.6 and 7.8. New tank setup about 3 months old. Last I measure was last week and I was at 8.2. Since then I have added 2 small clowns and a few corals. All other parameters seem to be in check (see below). Can’t really think of what would cause this but would like to try to nip it in the bud. Thanks!

Ammonia 0
Nitrite 0
Nitrate 7
Alk 9
Salinity 1.025

Forget the API test kit. I'd test midday and later in the evening to get the pH range - since it will fluctuate during the day.

Tested just now. Back to 8.2 on Red Sea. Left a window open last night for some air flow that seemed to help
