The muriatic acid was unpleasant... I see why people want to jam 15 pucks into a chlorinator... but I want to give my pool what it needs though. So I'm here to stay!
Ohhhhh that makes so much sense now!!!!Backwash when your filter pressure rise by 25% over clean pressure.
If you follow their chemical plan the backwash each week keeps the CYA from rising very quickly. You are dumping lots of water each week. That is how they try to make that process work for the pool season.
Time for you to fill out your signature. Lots of things about this pool we do not know that can change recommendations. Like an autocover and running your pump so much. Really not necessary.for the autocover
