    hi guys.

    need some help..have an issue with my calcium which dropped drastically from 400 to 340 n caused stress to two corals including my favourite purple tubinaria. ..I accidentally overdosed my kh which I think caused my calcium to drop..kh is currently at 11.calcium is at 380 n wont go any higher.i am dosing seachem reef advantage calcium but it struggling to increase calc..will I have to wait till kh drops?

    How is your magnesium? It affects the solubility of calcium.

    Yes overdosing kalk will drop Ca. Let alk drop naturally over a few days and or increase Ca slowly over a few days until levels you would like. Ca level of 380 isn't a train smash it's the sudden drop that causes stress. Your corals are most likely affected more by the increase in pH from you alk spike, make sure it stays below 8.6

    magnesium is sitting at 1400.i hav stopped dosing for kh and hav started increasing calcium slowly to bring it up . Hopefully the tubinaria recovers. I havnt seen any proper polyp extension and tissue has died away on some spots .orange fungia coral also took a knock

    I have a similar problem
    I can't get my magnesium down from 1600
    My calcium is running low at 330 (even with a reactor) and a KH of 7 & Ph 8.1
    How do i get my Mg down?

    kevimac..I know that some of the media that you run in the reactor also increases magnesium. My magnesium is not dropping coz the reef advantage calcium also buffers magnesium

    Aah, I'm using ARM with "high magnesium formula" ...

    I guess my SPS is grow just fine ... so no need to worry about the high reading?

    magnesium at that level is ok, adjust Ca no more than 10ppm a day.
    just remember all changes to be done slowly

    been doing tests and dosing calcium..my calcium has stabilised at 360..kh has come down to 8..i have hooked up my doser to dose 15 drops of calcium every 2hrs..will see how that helps.

    corals seem ok..turbinaria has shown better polyp extension
