Personally, my sumpless 90 gal system evaporates less than 3/4 of a gallon per day. I drip half of that at night after lights out and the other half in the morning. With a full container I get a thin stream that tapers off to drops about half-way through. I mix up 4 day supplies of saturated solution at a time and have never had any pH probs this way.
If your calcium consumption rate does not require using saturated kalk solution you could always drop the kalk concentration and up the delivery rate.
