    Can someone tell me how much Kalkwasser I’m supposed to use. I have all of my levels where I want them and have been dosing 2 part. Wanting to switch to Kalk in my ato but can’t find any directions.

    Started with 5 tbl spoons and it was too much. Check alk three times a day to see the levels. It is nerve racking for the first batch. Good luck

    Just remember, that stuff accumulates on the bottoms of water ever you mix it.

    1. Mix well

    2. Don’t let the ATO pump get so low it is taking the high density water at the bottom.

    3 empty ATO jug, every time you refill it and make the mistake I did by just adding more mixed water. End result, steady increase of alk

    What do you all do about all the stuff that accumulates in the bottom of the ato container?

    i use a rigid tube and keep it about 1/2" from the bottom and just toss that when i switch containers. i make the new batch at least a day before needing to swap to give it time to settle

    I do a quick rinse with R.O water every week when i refill it.

    If you mean during the week? Just make sure the pump isnt sucking from the bottom of the container. I use eggcrate ziptied to the pump to keep it about 3 inches off the bottom .

    I've heard of people doing both, I normally toss out what is ever left in my container (usually less than 1/2 gallon) and do a quick RODI rinse and refill.

    My ATO pump sits about 2"-3" from the bottom. I use 1 1/2 teaspoons per gallon. The calcium hydroxide precipitate that ends up in the bottom, stays there and is sucked out once a month, at least for me. I don't stir the sediment, just dose the clear affluent into my system.

    You could always look at a kalk reactor.i have never used one, but on came with my new to me set up- I plan on connecting and dosing from my apex for more precise dosing, but they can run via ATO pump and always have saturated limewater. You set them to mix the kalk that settles out to the bottom.

    Mix kalk in a gallon jug, let the precipitate settle out, then pour off the clear saturated limewater into your ATO container.

    Another Kalk ? Ok I am up to 1 1/2 teaspoon per gallon and my alk is stil dropping from 9.0dkh to 8.9 dkh daily. Should I ride this out and see what happens? Or should I up the Kalk to 2 teaspoons per gallon?

    If its consistently dropping .1 a day over a whole week, i would go ahead and up it to 1 3/4 tsp per gal and continue checking every day.

    just my opinion

    Anything over 2 teaspoons won't dissolve in a gallon of water and will just be wasted. I agree with upping it and checking it to see the results.

    I have raised my Kalk to2 teaspoons per gallon and alk is still dropping after 1 1/2 more weeks. Does this mean Kalk isn’t for me and my tank?
