My problem is efflorescence on the high side of my pool where high water table water actually comes through the grout in several areas. For the "thick" stuff I gently used a flat blade screwdriver and small hammer (think almost a jewelers hammer) to slowly chip the thick stuff off. Then I used the Purity Pool OS Out Spot Stain Remover for the cleanup work. Now, when I see it starting to appear I hit it with acid before it gets too thick, but when I need an acid addition anyway.Or maybe i will take a look at the device Tim posted. Just not sure how well it will work when it gets thick.
So, I don't have a test kit just have been using the strips that the pool builder gave us. I'm going to pick up the test kit you guys recommend and get a handle on this situation I haven't tried with anything other than my finger so it might come off easily.
