Rising Alkalinity

[Merv49]

I am experiencing higher alkalinity even though I've dialed back my Kamoer dosing pump and increased the PH in my calcium reactor. Also my acrapora corals seem to be loosing color. I just got a ICP test back and my water chemistry is spot on. I can't figure it out. I was running 9 dkh for a few weeks and now it's running 10.5 even though I've dialed back the pump.

Just a thought. It could be that the increase in Alk is a result of unhappy corals vice the corals being unhappy due to the rise in Alk. I don't run a calcium reactor, so I'm afraid I can't be much help. Any other recent changes? Hopefully someone with experience will chime in.

Did anything change, did you add or remove any hardware?

Didn’t change any hardware. It’s like the corals have reduced their alkalinity uptake. Most recent water sample results were almost perfect.
