so im dosing kalkwasser in a brs space saver jug do i need to mix every so often being i do not have a reactor also ive read that adding vinegar makes it more concentrated any help will be appreciated

Some will settle out in the begining when you mix it. That portion is prob not soluble anyways.
It is ok to stir it. I would just be sure to let it sit for a bit before dosing. You dont want the undissolved stuff in your tank.

Adding Vinegar to Kalkwasser

I've dosed my ATO with 2 teaspoons of Kalkwasser per gallon, but my alkalinity still drops over 0.5 dKH per day. I have a 55 gallon mixed reef with 4 SPS, 4 LPS, and a mix of 7 softies and leathers. I've heard of mixing in vinegar to get an extra teaspoon of kalkwasser per gallon, but I'm...

Norte that this is not a "free" effect. You will end up dosing a lot of organic carbon this way, for better or worse.

Vinegar does indeed increase the concentration of kalk. Basically it allows you to use more kalk and less water for tanks that don't have enough daily evaporation.

You have the first problem that Randy mentioned.

The next is that you lose the pH rise of kalk which is a big reason for using kalk.

Ok so no. Vinegar next question when is it a good time to dose otbive been dosing at night but still see no real effect ph gets to about 7.7 sometimes 7.8 but nothin higher than that

Are you monitoring alkalinity?

What is it and how much limewater (kalkwasser) are you adding each to day what size tank?

i have a brs space saver jug i beleive its a gallon jug ive been dosing 1000 ml over a 12 hour period with my neptune dos tank is 200 gallons total water volume ive been monitroing alk its 8.2 as of now i try to test at the same time everyday which is around 6 when i get home which i will do later today

1 L of kalkwasser, even if saturated, when added to 200 gallons of aquarium water only boosts alkalinity by 0.15 dKH per 12 h or 0.3 dKH per day.

If that is enough to maintain alkalinity, it will have only a small effect on pH and it doesn't matter much when you add it.
