When I used to drip Kalk, I did it 24 hours a day. So yes it should be fine. Just to be sure, check your pH during the day to make sure it doesn't get too high.
I also drip 24/7.. but I gace that up because I loose too much water and the food bags aren't nearly enough... so I am just going to make an auto top-off with a 5-10 gallon bucket with pre-mixed solution and a powerhead in there to keep things mixed.
