Hi there no .Your base water is 80ppm (which is very good) use Cal-mag to get it to 150ppm to start. you could practice if you like fill bucket with tap water and add mls of calmag until the desired 150ppm or slightly over is reached. you will also need to wait at least 24 hours before using chlorinated town water bro 
Also you will need to find out if your city water supply is using chlorine or chloramine, Chloramines are not as effective and do not dissipate as easily as chlorine. Chloramines are difficult to remove and cannot be removed by boiling, distilling, standing uncovered or by some reverse osmosis filters. The disinfection byproducts of chloramines (iodoacids) are more toxic than chlorine. Chloramine vapors can accumulate in indoor air (small areas, bathrooms, kitchens, etc.). just check online at your local water dept. to check the quality of the water and which they use.
