calcium question

[jiffy]

like a dumb dumb I've been dosing purple up everyday for the past couple weeks, which has done nothing for my coraline growth but it has raised my cal to 600-620. macro algae doesnt look so good and a few zoas are closed up. is there a way to lower it without doing a massive water change?

no, just do small ones every dat about 5% of your tank or less
