ph testing

Hi all, I first started here last year trying to get my pool right. I was not able to buy a test kit until now (I got the TF Pro Salt) and it showed up yesterday and I just finished testing. Here are my levels: pH + Chlorine Testing block - Cl - 5+ | Br - 10+ | pH - 8.2+ (see photo) FC - 7.5 CC...

I can never get a good color tone match on the plastic kit. I do get good matches on our 25year old Guardex test kit using porpoise test bottles from pinchapenny. Does anyone else have this problem, or is it just me? Also, is there a recommended best tool to measure pH?

Hi, for those of you using the Apera PH60 pH tester, how do you store the pen and all the associated solutions once you've opened them all and are storing the pen with the KCL storage solution in the cap? The supplied case (photo) is fine for shipping, but pretty much useless once you open all...

Hi all. People seem to post regularly saying they have trouble comparing colors for the standard pH test. Certainly color blind people must? For me 7.8 and 8.0 look almost the same. Of interest because 8.0 is my trigger to add acid. It would not be super hard to build an app that uses a phone's...

I have two ways to test pH: Standard Taylor test kit from TFTestKits Aptera ph20 digital (originally purchased b/c I was having trouble differentiating colors on the Taylor kit and to get more accurate high/low readings during startup as our startup "guy" was all over the place) The digital...

Hi All, Prior to adding 50ppm of borates to my pool (I used boric acid from Duda Diesel), I had very high pH. This was probably due to my SWG and spillover spa. However, the acid demand was always quite low. Sometimes a single drop would take that sample (K-2006) from a fairly dark red back...

Like many, I was hit with some freeze damage during the winter deep freeze in Texas. I was fortunate to have a whole home generator which saved me from more severe damage. I did not however escape unscathed. My Intellichem JellyJar cracked as did the housing and intake filter. Anyone who has...

I just received a SpeedStir and noticed that there is no 44ml level on the enclosed vial, but in order to test with Taylor K-2006C a 44ml sample is required. There is no alternative testing method for smaller samples as there is for CH and TA. Do I need to use the manual Ph test included with...
