Approx. how much lime is used for 5 gallons of RO/DI?

Does it entirley depend on your current tank specs. or does the kalk need to be at a certein level regardless?

For example, say you have a 100 gal high Ca demand tank that you try to maintain at 400ppm Ca, 8dKH, 8.2 pH etc... what would be the recomended dosage?

Correct me if I'm wrong ( I am a current 2-part user ) but you guys ( who use kalk ) you premake the lime water ( via 5 gal bucket or the like ) and drip it in the tank overnight... is that right?

Thanks and sorry if my question is unclear

Don't expect Kalk to hold your levels if you have a high demand, no matter how much you use. It just helps a little.

The water should be premade a few hours in advance.

I use 1 well rounded tsp. per gallon, and yes I do drip it overnight. The PH of the mixture is so high, that it could be disasterous to add it all at once.

It does depend on the tank demand, but 1 level teaspoon per gallon of top off water (added very slowly) is a good place to start. Change the dose based on alkalinity after a few days (not calcium).

I make up 88 gallons at a time and use it over a few weeks.
