My alkalinity as suddenly started to drop like a stone, but no sign of precipitation, and dosage goes into good flow area. I don't know why.
I maintain my kH around the 7.8-8 dKh mark. My Ca 420 and Mg 1230. I dose Triton methods Core 7.
I was away for a week and my pH increased from 8.2-8.3 to 8.3-8.4. The last few days the alkalinity demand seemed to skyrocket from 20ml of 3a&3b Core 7 combined to nearly 40ml, and even then there was a gradual drop of the dKh to 7.6 dKh My tank is lightly stocked with a variety of LPS and SPS corals of small size. No matter what I dosed the demand still seemed to increase. It seemed way too high, and I suspected a problem so cut off all dosing for 2 days. The kH dropped from 7.6 to 6.4dKh.
Previously the tank had been very stable, with a slow gradual increase in 3a&3b usage.
Please help
