Really like the newer test strips with the purple for SmartChlor value. Even the other tests, the colors seem more consistent across the pads. I’m concerned how deep plum purple mine will test. It’s after I put a new Chl cartridge in and clean filter. I’m beginning to wonder if the @ease cartridges I order from Amazon that come in covered in fine chlorine dust, aren’t recycled and have just crushed pool tabs put in them?! Thus dissolving quicker, increasing Cl & not the correct Dichlor product! 😡 Will go back to pool store for cartridges! But these new test strips are so much better.
