Newbie here. I've been using Leslie's Power Powder Plus shock and wanted to try using their 3" Jumbo Tabs to keep the chlorine level up. The clerk at the store told me that it's ok to use both products, tabs daily and shock weekly. After getting home and reading the chlorinator instructions, it says to never mix Tri-Chloro (jumbo tabs active ingredient) with Calcium Hypochlorite (Power Powder Plus). I'm confused with what seems like contradictory information. Can someone please ease my concerns?
