macgd016 Posted September 15, 2011 Report Share Posted September 15, 2011 Before any one suggests a Taylor test kit let me say that they are almost unobtainable in Europe and if you can find one they are very very expensive as are the Plaintest Pooltester kits! So we are forced to use strips, OTO or tablet based kits. I have given up with strips as they are a complete waste of time but now use a bog standard OTO bottle kit that measures Total Chlorine and pH and a tablet kit that reads pH, TA and Free Chlorine. However, I still can't get to a position where I am happy with the readings I am getting. I find the OTO kit easy to read or at least it is easy to differentiate between 4 & 2ppm chlorine and it is easy to see the difference between 7.2 and 7.4 pH. However, as OTO only reads Total Chlorine I bought a tab based kit so that I could read Free Chlorine and TA. The problem I find with this kit is that I find it very difficult to see much difference between 2 & 5ppm chlorine, the TA reading is very subjective as none of the colours I get really match the test colours although I am getting more used to this one, but the main issue I have is pH. My pH tends to drift up from 7.4 to 7.8 using my bottle tester but my tab kit, which has a very similar colour gradient, shows 8.0 all the time, until recently that is. My last bottle reading showed a VERY clear 7.2 and the tab kit then showed a VERY clear 7.8. I emphasise the VERY because just for once the readings on both kits were very clear indeed. So which kit should I trust, if any? I have tended to trust the bottle kit for pH and double checked the OTO chlorine with the DPD tabs but its irritating to have to use two kits and still be unsure of the readings! I am beginning to think that an electronic reader might be better, does anyone have views on the Aquachek TruTest? Quote Link to comment Share on other sites More sharing options...
