How much liquid chlorine should you be adding weekly to a pool with 70000L?
After a few weeks of testing your pool you will become familiar with what it takes to adequately control the chlor. content in the pool. Each and every pool is different. It could take endless amounts of chlor. if you do not have any conditioner in the water. Haven’t calculated the amount you list into gallons but would think one to 2 gal at a time at least once per week. TEST THE WATER EACH TIME.
