    WHat is your KH?
    Having such high readings could have an impact on your corals. Such high calcium you risk having a snow storm.
    Easiest way to bring it down is to stop dosing and let it fall on its own. Otherwise waterchanges will help, but you dont want to drop any parameter too quickly.

    what are you dosing to get it this high...if it's kalk wasser you should not just stop dosing but scale down on the mix over e vew weeks...my readings are the same ca even higher ...it wont efect the corals...most guy;s batle to keep there ca and mg up...and how manny corals do you have...like 459b said water changes but that will be quite a few big ones ...you need to get the kh up aswell...its way to low..

    And magnesium?
    Seachem products. If your calcium is that high, then stop dosing and wait for the level to drop to normal range (400-420) before starting dosing again.
    What salt are you using?

    I would stop dosing any calcium suppliments at the moment and at this point dont add any KH additives until your calcium reaches the 400 mark. Your ionic balance is way out in your water and you wont be able to raise KH until the calcium comes down.

    Stop all dosing for now, but keep an eye on KH.
    Ca - around 400
    Mg - around 1300

    Ammonia a bit high. What is your temp as ammonia toxicity is related to temp.
