I use a dripper made for reptiles that holds 2 liters of water, and has a plastic dripper valve. I put the lime in first and then the vinegar. The vinegar reacts with the lime dissolving it and converting it to calcium acetate. Then I fill it with water. The calcium acetate dissolves more quickly and completely than the calcium hydroxide. I drip it slowly into the take to avoid drastic pH swings, but even the one time that I had a valve malfunction and it all ran in a couple minutes there was no noticeable harm. Of course, I don't have any really sensitive livestock.
When the calcium gets really high I skip a day or two of kalkwasser and just dose with vinegar.
