So I got the 125 up and going and the last 2 days I've noticed a swing in ph from 8.0in the evening to 7.92 in the morning is this normal or should I be concerned

That's fine.

Normal. What's occurring is that during the day (lights on), the CO2 is being consumed in photosynthesis....being turned into sugars and other fine things. At night, no photosynthesis, so the build up of CO2 in the water is turned into a weak acid, driving down the pH. That's actually a small drop. Others see a larger drop in pH because of the CO2 in their house.
