Can i use this product with my poolmaster test kit? not just for measuring ph, but also for acid demand test?

U put 5 drops in 44 ml of water ,yellow is 7.0, purple is 8.0 so 7.4 is a kinda orangy pink peachy. u will need the acid demand and base demand drops to add to ur test. So lets say ur pool is at 7.8 ph and you need it to be 7.4 You add however many drops it takes to change its color to peachy,then U figure how many cups of acid in the pool equals 1 drop probably 1 for a 15000 gal pool , start with 1 cup of muratic per drop for a 15000 gal pool Acid Demand #: R-0005-A
