There has been, and always will be, resistence on this site to use of anything other than the taylor test kit or a color block to test ph.
And I remain as puzzled as ever at responses to the ppl who are reaching out for help because they have trouble with the very subjective interpretation of reading color variations from a ph color block. The response to those with problems with these color issues is too often, "don't try anything else except the testing method you are having difficulty with."
We''ve been down this road before...the contention that PH meters are too much of a hassle, or time consuming. Can't be trusted,etc. Typically, this is accompanied by the misplaced belief as to the necessity of dual calibration...this notwithstanding that dual calibration is unnecessary for testing pool ph (dual calibration being required for things requiring far more narrow and precise ph measurements such as aquariums and ppl who do home brewing - hardly the case with the relatively wide range of safe and acceptable pool ph levels.
I have had excellent experience with ph meters. I use it because I suffer from a mild case of color blindness. Others have had equally good experiences. For a myriad of reasons which have been raised in countless threads before, use of a ph meter is an acceptable and reliable means of testing your ph for those of you who, like many here, lack the ability and/or the confidence of relying on ph readings from a color block.
If you want to pm me, I can give you the make/model number of a reliable and inexpensive ph meter that I have used successfuly for years. I can also provide you with a simple and brief tutorial as to ise ofbthe ph meter that, contrary to many views expressed here, is not the protracted exercise it is made out to be. Or you can simply do a search on this site using "ph meters" as the search term and you will come across posts about ph testing that contain useful information (tho you will have to filter out a good deal of well intentioned but misguided efforts intended to keep you far away from what evidently is perceived as an instrument of the devil).
