Had a little mishap with my reef keeper last night and it pumped all the calcium into my tank instead of following the timer I set for it and my calcium is testing well over 500ppm. Is this a huge issue? My alk is at 9 dkh and mag is 1200(I know this can come up, I already dosed accordingly.) Everything in the tank looks fine I just want to make sure I don't need to do a water change. Thanks.
