Im running IO right now, and Cal/Mag is ,low. Originally was going fowlr but now getting LPS and softies. What should I dose with? I have some Liquid Cal and mag, Salfert brand I think. But using alot of it just to get to NSW levels. When this bucket of salt gone, Im switching I think.

You can get bulk Ca and Mg from Chem Master (littlesilvermax) . Here is his thread

Thats what I use to bump it up. Works great

hey thanks i'm actually considering kalk dosing for once. the whole thought of my pH sky rocketing always kept me away from it, and i ended up dosing alk & calcium individually. how does it hold up as a buffer though, i see you also dose a seperate calcium supplement, is this to make up for the kalkwasser?

Kalkwasser should add cal and alk in approx. the same ratio that your corals use them. For years thats all I ever used

Here is my high tech kalk dripper

I used to have a valve to control the drip rate but I kept breaking them so I now use an even more high tech method :razz:

If you want a slower drip just tighten the knot :mrgreen:

thats a good idea marie i'll have to set something like that up in a couple days, get an airline check valve and some kalk pretty soon. is that a weeks worth of dosing, or more?

Thats a 6L container and for me its 1 nights dosing (I also use a calcium reactor).

When you get started you will have to monitor your alk daily to make sure you are adding the right amount of kalk for your system. 2tsp per gallon of RODI water will give you complete saturation with a ph of something like 12.65 (or there abouts).

What's the check valve for?

Its to control the drip rate of the kalk

about what drip rate do you set it at, or in other words how much solution would you drip for a 40 gallon?
