This is what I advise everyone starting to dose kalkwasser to do
Kalkwasser
- Know your alkalinity consumption for 24hrs. I recommend testing 3 days in a row at the same time and average the consumption over those days. For my example we’ll use a 100g system with a consumption of .5dkh per day
- Go here https://reef.diesyst.com/chemcalc/chemcalc.html
- Enter system volume
- Use 8.0 as current alkalinity
- Use 8.0 + (alkalinity consumption for 24hrs) as desired alkalinity. So 8.5 for the example
- Note – The actual alkalinity of the tank doesn’t matter, just that the starting alk and desired are separated by the 24hr consumption. This is because it will take the same amount of kalkwasser to go from 8.0 to 8.5 as it does to go from 7.3 to 7.8
- Select “limewater saturated” as the product being used
- Hit calculate
- This will give you the dose needed for 24 hours. Spread it out how you like, but the more times you can dose the better.
- Don’t just blindly add kalkwasser without knowing you’re alkalinity consumption, it may raise ph but your alkalinity will go up too!
Now, as for a dripper. BRS sells a dripper kit. You'll need a container to dose from. These work pretty good as long as you can gravity feed it into the system, and you are commited to filling the container everyday or every couple days as needed.
Build your own kalkwasser dripper with the DIY Kalk Dripper Kit from Bulk Reef Supply. Just choose the storage container with lid that works best for you. Kit Contains: 16” Long - 1/4” Clear Acrylic Tube 1/4” Mur-lok Inline Ball Valve 2 - 1/4” Mur-lok Push Connect Bulkhead Tank Adapter 2 -...

As for concentration of kalk, normally people suggest 2tsp per gallon of water in the container. I would suggest slightly less, like 1.5tsp or 1.75tsp per gallon in the dosing container, simply so you won't have any (or very little precipitation at the bottom of the container).
