After reading forums on kalkwasser I started using pickle lime and the results on the my ph,alk and calcium are amazing. My ph has gone from 8.0 to 8.4. I could never get it much above 8.0 . I had been adding buffer and calcium on a regular basis, chasing the correct parameters. Last time I checked alk was 8.0 and calcium was 390. I added 2 tsp. of turbo calcium and retested at 420. Everything looks happy. I am happy not chasing the parameters, justing adding lime water to my topoff.
