The recommended levels page of tfp says that CH for swg pool should be 0-300 (don't add). My newly installed hayward h250 manual says that it should be 200-400. If too low it could be corrosive to heat exchanger. Which should I follow? I current get a reading of 50 and in the past never added anything.
Also it says that FC should be 1-3, but I usually keep it closer to 5 since my cya is 70. All other stats seem to be comparable.
