Lower pH?

[Tyler Sullivan]

Hey yall question.

My pH is 8.63 via apex probe and Red sea kit came back as roughly 8.6. I dose kalk but it doesnt dose unless my ph probe reads under 8.0. My probe says it bounces between 8.56 to 8.67
What could I do to drop it?
All corals except for some sps are doing great but I have no coraline algae growing which concerns me. Tank has been up for 3-4 months now.

Thanks

Ph around 8.6 is fine. I would not chase Ph. You will never catch it. Its more important to keep alk stable. 3 months is a new tank . I never see coraline until after 6 months to a year. Just keep your calcium and mag up and it will happen.
