Can you dose with baking soda to raise ph?
Baking it at 350 degrees for an hour or so will separate the sodium bicarbonate from the nasties it tends to accumulate, mainly CO2. Baking soda is very absorptive, that's why it is often used as a deodorant in refrigerators etc. This will cause it to increase both Alk and PH(CO2 drives PH down). Un-baked baking soda will lower PH as Hara pointed out. HTHCan you dose with baking soda to raise ph?
If all is well lots would say 7.8 is ok. That is where mine has always been with no issues. jmo
What time of the day did you test? PH is low when light is off
