Also - remember that if your chlorine or bromine levels are high the test strip will not be able to give you the correct readings on pH or TA. 8-)
Ah, very true Chas and I often forget to mention that. High chl/br readings will "bleach out" pH readings and make it look much higher than it really is. Always test pH when your sanitizer reading is in proper range!Just out of curiosity ndabunka, what's the relationship between low calcium and having to add pH down? Steve
