I'm brand new to pools. Just bought my house in Feb. I had a pool guy, but he was inexperienced and never showed up so I fired him. I was recently told I made a very bad mistake and need confirmation. My pool is in ground, 20x40 3ft to 8ft. Estimated 33000 gallons. I had the pump, liner, and sand filter all replaced. Since owning the pool I've added 9lbs of dry stabilizer and used trichlor tablets in my skimmer. I was told I needed to shock it after rain and heavy use so I add a couple scoops of shock which is calcium hypochlorite. I also just bought 35 lbs of cal-hypo tablets to use in my inline feeder since my stabilizer is at 35 and I don't want it to increase Someone just told me a screwed up big time because I'm not supposed to mix chlorine types... am I in trouble here? Please advise
