Lol, so I'm very new to doing things the TFP way (and pretty new to having a pool at all). I've read a ton and now I'm trying to SLAM my pool (after some instructions I was given on a different thread). I have a couple questions I couldn't find the answers to. First of all, how do I add chlorine? It's 12.5% liquid chlorine. So far I've just poured it in front of the jet but wanted to make sure that's okay. And when should I backwash my sand filter? Thanks!
