How fast can I lower Ca?

[timocean]

Due to a measurement error, I accidently dosed too much Balling light Ca. Now ICP shows a Ca value of 590. Other values are in range. How fast can/should I lower the Ca? What water change schedule do you recommend? Tank is 120g, salt TM Pro Reef. Thanks!

It's not the end of the world. Just stop dosing Ca and continue with your regular water changes until it drops back naturally into the desired range.

This is what I was hoping for, but didn’t dare to.. Thanks!

My parameters occasionally go outside the boundaries that I'd normally like to keep (like when I dosed some epsom salts to treat an injured fish and it spiked my magnesium).

As long as you're not exceeding it for months and months on end the occasional spike is easily tolerated.

I agree just don't dose it while calcium declines. Exact calcium levels are not very important, IMO.
