Alkalinity and CO2 Scrubber

Due to low PH 7.8 - 7.9 I added a CO2 Scrubber. PH now 8.1 - 8.2 and staying fairly steady. But now demand for dosing Sodium BiCarbinate for Alkalinity has increased significantly. Home watching today and in a 4 hr span Alk went from 8.9 to 8.4. Added 60ml of SBicarb to raise back to around 9. Another 4 hrs later same thing. Is this normal? Ca = 455 Mag = 1300.
