For those of you I spoke with at the meeting, this is why I am hesitant to shift to an auto doser. For the last two months, I have added just a hair under 3/4 tsp Baking Soda every day to maintain my alk at 9.75-10. I noticed my salinity was a little low Saturday so I topped off with 1g salt water at 1.025, to bring the tank up to 1.026. That evening, my alk was 10.6, so only added 1/4 tsp BS. For the last 3 days I've only dosed 1/4. Again today, my alk was 9.96 and yesterday it was 10.02. So it would seem that my tank is now using less alk out of nowhere. Calc has maintained at 430. Is this normal?
