Thanks, I suspect my calcium level could be about or over 550 as it takes over 35 API cal test drops to reach the endpoint (but I can't be sure). Just to clarify on what you said above... should let it adjust by its own over time or by using baking soda?
I would not do anything about the calcium.
I would maintain alkalinity.
