Mg cal alk which order?

What is the most effective way to dose a correction so that I get maximum uptake and reduce precipitate ...

Mg 1150
calk 360
Alk 10

 

Make sure you dose cal and alk at different times. I dose cal in the morning and alk in the evening. Give the cal at least an hour to dissipate before dosing alk. Mag can be dosed with your top off water.

*Your alk is touching the high side, dosing cal will lower that.

 

Should I move mg up first then calc for solubility?

 

Yes; always adjust your Mg first.

With it as low as it is for you, you will not be able to keep Ca stable until you get it to an acceptable level. Do not raise your Mg more than 100ppm per day. Shoot for 1350ppm or so, than adjust your Ca (no more than 50ppm per day). Lastly, adjust Alk (no more than 1dKh per day). Don't try to do too much at once; work on only one thing per day.

 

Sorry I was just thinking of when to dose, my bad.

+1 to evolved's recommendations.

 

Perfect...



Perfect. It's been many moons since I've had to dose. Water changes always done the trick.


The other issue is I'm trying to use up a 1/2 box of IO crystals until reef crystals go on sale. I have been penny wise but params foolish.

 

And that'd really explain it.

IO is notorious for having low Mg, right around 1150. This, in turn, will cause you Ca to drop.

 

Once you get them stable and to where you want to be you should look into something to keep up with the demand. Either 2-part of Kalk. I choose kalk because it is easy and I just add to top off. Keeping up on water changes will keep up with the mag.

As others said look into another salt. I tried the ESV salt and couldn't be happier. It is different because you mix all four parts instead of pouring in one thing. My corals seem to be happier.
