Low ph help

[Jphvav90]

My tank has been up for over 2 years. I have a neptune system that said the ph was 8.2 but then I lost 2-3 corals and I did all the manual testing then re calibrated the ph probe and it reads 7.8 it's back to 8 from changing the co2 scrubber media but is there anything else I can use to prevent it from dropping. I use red sea products for dosing.

Baked baking soda will bring up pH. But be sure to monitor your alkalinity while doing so.

Have you tried running an airline to an airpump outside to see if that alters your pH. (FWIW corals don't have issues with calcification until pH drops to 7.6.)
