I use the pucks and liquid chlorine interchangeably and together. I use the tri-Chlor tablets for addition of stabilizer and sanitization, but throttle it back depending on needs of CYA. I usually pull the dispenser if I’m home for a while and solely balance with liquid Chlorine. It’s worked well for me. I have TFTestkits stuff and it keeps me on target as I monitor levels bi-to tri-daily. I would burn thru pucks and chlorine in our summers here, monitoring CYA along the way, and now that water is sub-70 degrees I usually keep one puck in the dispenser, replacing it as it dissolves, and add a gallon of chlorine every 10 days, and that seems to do the trick. When water temp rapidly drops 30 deg in 3 weeks time during our season change is when I see pools then turn green due to high CYA and low chlorine. I pull all stabilizer products for a while the last week in September until about this time, and my CYA settles from 50 to 30 and then put the single tablet in, but that’s just unique to my pool.
