I have an Infinity spa (350gal) with a prozone ozonator/ salt chlorine generator. My chlorine levels are high due to extra salt and filteration cycle time but my ph is high and my ta is getting lower as I try to bring down my ph. What is the best way to balance this out? Is there a quicker way to reduce chlorine levels?

Generally, you balance alkalinity first then balance ph. To lower chlorine fast you can buy Chemout. Sodium Thiosulfate. But I'm sorry I don't have any experience with chlorine generators in SPAS.
