Help With Kalkwasser

[Radiography14]

Hi there

I was wondering if anyone could help me with this.


I have mixed a bunch of kalkwasser in a 20 gallon rubbermaid container today and i stirred it with a powerhead for an hour ,THEN LET IT SET FOR 2 HOURS then i kept the cover over the top and decided to test for alk and calcium content.

my alk or hardness tested just right at a 12
my calcium tested 120

what is wrong with this pic?

after the stirring with the powerhead the water set for 2.5 hours when the testing happened?

this is going to be used as top off water in my tank. this replaced the evaporated water.


are these levels where they should be?


thanks for reading
P.S I HAVE A 20 GALLON TANK

How much kalk did you add? Looks to my like you didn't add enough kalk.

The carbonate hardness will show different results between freshwater and saltwater. Id test the parameters of your tank after adding the kalk, test in the morning to give the chemistry to do its bit.
If you find high alk and low calc in the morning, then maybe you should try a calcium supplement on its own, magnesium may need to be added to assist the calcium levels as well.

Make sure you have test kits before adding magnesium just in case you dont need it.

Check out the reef chemistry forum and start reading. There is many links discussing calcium, alkilinity and magnesium. Alot of good reading.

Hope this helps a little.
