Hi guys
I made a mistake and dosed too much CA
it is 620, how can I lover it? corals and fish are doing good, but not sure how long I can stay like that
doing weekly 10 gallon water changed isn't reducing it
I have 91G system

thank you

Water changes are the only way to lower it, but if you can maintain alkalinity, it is OK to just let it fall naturally.
