I use liquid chlorine from ace hardware(hth brand). I ran out of it and ran to ace to find out that there is a recall on it and they didn’t have any in stock. Should have done by next week. For some reason the clerk recommended 3” inch tablets. I’ve never used the tablets before. Can I mix and match the liquid chlorine and tablets? I’ve put in the recommended liquid chlorine amount yesterday. Should I use the tablets or should I just run out and buy liquid bleach? Also on these bottles of both the liquid andn tablets it says not to go over 4ppm of available chlorine. I use the recommended target of 4-6 ppm. Is it harmful to go over 4 ppm? I remember a while ago that someone said not to use the tablets cause it’s hard to keep the recommended levels? Thank you guys
