My ph is between 7.8-7.9 should I be chasing the magical 8.3. If so how do I go about it. I tried opening all of my windows in the room my tank is is in and it seemed to drop lower for the day the windows were open than bounced back the next.( could of been something weird I did). I have a 75 gal rimless with only 5 fish so it’s not over stocked. Any ideas thanks everyone
