Can anyone help determin how much kalk i need.

[James Mikell]

I am currently dosing seachem reef fusion cal and alk and am only dosing 3 ml of each to maintain levels.I am waiting on my co2 scrubber to arrive to see if i can raise ph. One thing i considered doing was switching from 2 part to a kalk stirrer to help raise ph. Can anyone tell me how much kalk i would need to dose to maintain the same levels or if it would even be worth it since my consumption is so low still.

Kalk is actually better than two-part in low consumption tanks, in my opinion. We would need some more information. Tank size, current alk consumption per day?

Here is a calculator to help: http://reef.diesyst.com/chemcalc/chemcalc.html
For example, 1 gallon of saturated kalk will raise about 1dKH in a 100 gallon system.

With this calculator you can check exact amounts and values you need. Easy to use, helped me dial my kalk contribution un a pico reef in no time!

Current consumption is 3 ml per day of seachem reef fusion the total water volume is aprox 65 gallons. I used that calculator before to figure out my current dosing needs but it wont tell me how much kalk i need to maintain those levels.

Playing around with the calculator... It looks like your tank goes through about 0.1-0.2 dKH per day.

That would equate to somewhere around 1/10 of a gallon of saturated limewater solution, if you want to use saturated kalk.

Being that its such a small amount would it be worth switching over? Would i see any noticeable rise in ph from only dosing 1/10 of a gallon?

Hard to say.

Adding 1.25% of the tank volume with saturated limewater will boost the pH instantly by about 0.7 pH units, but the effect rapidly wanes as the system pulls in more CO2 from the air.
There's no way to determine in advance how much using limewater will boost pH overall, but be certain alkalinity does not get higher than you want." RHF
