I started keeping lower ALK now that I’m using AF Reef Salt, which closely matches my batch.Not doing anything special. Its high in middle of tank, high flow. Tank get phyto /oysterfeast 1x every 2 weeks, wc 1x every 2 weeks. Dose kz 1234 1x/week. My alk consumption dramatically went up. I used to dose 30-32ml ESV 2 part to keep it at 7.8. Now, I'm at 48 ml.
