View Full Version : how fast can you raise magneisum??

09/17/2010, 07:08 AM
I had my water tested professionally and come to find out my magneisum is at 1050. i have done the calculation and it will take a total of 900 ml to raise it to 1300. how quickly can i add this? I know when you use the BRS stuff they have you add 12 fl oz. at once. can the same be done with ESV B-IONIC?

some people dose all their mag at once. though i like to break up my doses. I add smaller doses a few times a day for 2 or 3 days to get mine right. it is good to start slow if you have never dosed berfore, just to make sure everything is ok.

I stick with 100 ppm per day for Mg. If you are using the reef chemistry calculator (http://reef.diesyst.com/flashcalc/flashcalc.html) it will tell you that in the notes. :)

you can dose it all at once but i would split it up over 3 days.

why not do a water change to help bring it back up?

Concern is stressing corals, so 100 ppm per day is recommended. Best to split it up twice a day, so 50ppm in morning and 50ppm in the evening is best if you can.

I also remember it shouldn't be dosed with Calcium at the same time.

Partial water changes won't make a measurable increase in Mg by very much. You'll need to use an additive (Kent Tech M or Mg Chloride/Mg Sulfate mixture would be my choices).

I am curious how long you can wait before you dose calcium after you dose your magnesium?

what happens if you dose them too close to one another? think i've been falling prey to this mistake...

Calcium and magnesium can be dosed together. Dosing alkalinity and calcium requires a bit of care to make sure that the supplements disperse before precipitation occurs.

Where was the water tested? People have had problems with some of the online companies that do testing, such as AWT.

it was tested at a few lfs,,then it was done at a good place that does reef tanks and ONLY reef tanks with a $100 test kit so i know its low
