So here's a question - I've been playing around with my CO2 scrubbing and Soda Ash dosing to see if I could stabilize my pH and avoid it getting too high during the day. Now that I have an air exchanger on the house and a scrubber on the skimmer, my pH can exceed 8.5 during the day. So I thought I'd try an experiment and dose my alk at night and that did smooth things out a bit. I was now in the 8.25-8.4 range BUT I tested my alkalinity at the end of the day today just for fun and noticed it dropped .6 dkh during the day (more than I'd expected!).
So here's the question - what would my inhabitants be happier with - a stable alkalinity but big daily swings in pH, or lower pH swings but a bigger alkalinity that fluctuates daily?
