Kalkwasser Help

[sudman]

Hi there ,

I am relatively new to the hobby ( about 2 months in ) and I just got a Dosing system ( Jebao DP4) and some kalkwasser.

I have a 120 gallon tank , aprox 45 gallon Sump of which 30 gallon is filled including the Refugium.

My Dosing container is 3.3 cups / 800 ML and my current tank parameters are :
PH - 7.92
Calcium - 420

I have just started filling my tank and got my first coral today - Green Star Polyp . I would like to add more and also maintain levels in my aquarium to help with fast growth.

How much Kalkwasser should I add to my 800 ML Dosing container ? How often and how much should I dose ?

Thank you !

BRS has a calculator on their website for figuring out how much kalk to dose. Generally what you want to do, is monitor dKH and calcium levels, see how much they drop in a week, and then use that to calculate the dosage. Keep doing this over time, because as your system stabilizes, and coraline algae and corals start to grow, the uptake will change.

Note that a GSP will likely not uptake any appreciable amount of calcium or dKH, but coraline algae will. In reality, if it's just coraline and GSP, water changes will more than make up for the drawdown.

Alkalinity is the main parameter you’ll want to watch. It’s unlikely that you’ll need kalk for quite a while. The main reason for it is to add alkalinity and calcium in an appropriate ratio. Don’t use it just to bring your ph up, because it impacts more than just PH.

Pretty much the only thing in your tank using up alkalinity and calcium will be coralline algae until you add SPS corals and to a lesser extent, LPS corals.

Look up the article by Randy Holmes Farley called “Not your grandmother’s pickling lime.” It will make you plenty informed about Kalk.

Thank you . How can I grow Coraline Algae ?

It just happens with the right water conditions and by introducing it on live rock or even something tiny like a crab sell or snail shell.

It looks cool on rock....but is a pain on equipment and I think it looks bad in glass (some people like it).

Just so happens one of the R2R sponsors posted this video today!
