Confused!

Issue with my 180g mixed reef (a ton of softies, huge Maxima, shrooms, 1-2 SPS, several LPS)...I overdosed Ca buffer a few weeks ago (Ca shot up to 510). I turned off my Ca Reactor waiting for the Ca to come back down naturally. But it won't! AND, interestingly, my Alkalinity is staying put at around 8.5. Every so often it dips a little lower. This has been going on for a few weeks. How is it that with no Ca Reactor online, no buffers....the Ca and Alk reading are staying stable?

I would get a second opinion on the test kits, if that's not too hard. Does the tank get Kalk or any other calcium source at all?

Also possible that the readings are accurate and the spike temporarily stunted growth, it can take a few weeks for everything to settle back in and start consuming again.
