Moral of the story: If you are using a CO2 scrubber and the media seems depleted either change it very quickly or monitor ALK like a hawk to prevent any swings...
Thank you for the heads up.
I just installed my recirculating CO2 scrubber since last week. I noticed my ALK dropped from 7 dkh to 5.5 dkh after 3 days of running scrubber!
I had to up my neptune doser to compensate for the sudden increase in ALK demand. Did not think about the downside when PH drops back down and what would happen to alk levels then!!!
My pH before scrubber was from 8.1 to 8.3, after scrubber it is 8.3 to 8.5.
