calcium question

rockman · 08-21-2007, 08:46 PM

Ive always had a problem with calcium being low but I never cared cause I wasent keeping any stony corals at the time.Ive been testing my calcium every day and adjusting accordingly to get up to 460 ppm

Ive only got a few frags in the tank but over nite it droped to less than 360PPM

Is there something im missing here.I cant keep doseing bionic like that everyday and it cant be good for the corals to be jumping up and down like this.I thought I herd mag has something to do with calcium ,should I get a test for that?

I am using reef crystals salt and its low on calcium from the get go also.
Like 360ppm or something.Help I am realy puting alot of effort into this tank and do not wanna ruin my beautiful frags.

460 IMO is a bit high. Yes you definately should check your Mg and also what's your Alk?
