do a search or read the dirrections on the kalk jar.
I use the limewater this way....
glass 1 gal jar set on top of tank.
fill 1/2 way with RODI (or tank water)
add 4 table spoons lime.
cap, shake well.
let settle 4 hours or so.
using an airline tubeing, create a siphon 1/2 inch up off the bottom of the jar.
cap off the end with a plastic needle valve.
open valve to allow one drop per second drip into the tank.whensiphon is broken, discard the crap in the bottom of jar. DO NOT USE IT.
you only want the clear liquid.
