My tap water as a PH above 8; My Alkalinity is at least 200 ppm. I struggle with high PH bounce and I am assuming it is because of my high Alkalinity pointed out in a earlier post. I will admit,I use test strips to read my Alkalinity and I read this test strip before I add Bromine so I will not get a false reading. 200 is a "educated" guess. I live 35 miles from a store that can check my water and they currently are pissed so.....
I use hth spa Ph decreaser;91% sodium bisulfate. It takes a lot of this product to lower the Alkalinty; I have added at least 4 cap full's 1 at a time. I add them with the blowers going for 20 minutes and then recirculate for 2 hours before checking again.
Using 200 ppm and a PH of 8.2 and a Jacuzzi that hols approx. 380 gallons, How much of this above Ph decreaser is needed to lower my Alkalinity to proper value and to get my Ph to stay at 7.2 to 7.6?
Should I be using a different product to bring my Alkalinity down?
Does Muratic Acid work better to lower Alkalinity? How much do I need of this with the above starting numbers?
Currently after 2 days, My Ph is approx 7.5 and by Test strip my Alkalinity is around 150 ppm. I use bromine as my sanitizer and I use a non chlorine Oxidizer every week. I have not added any Oxidizer yet; I know this screws up everything.
I will have to order chemical on line. I can get my current product at Walmarts and I can get Muratic Acid at the Lumber store
