sorry to highjack your post just a quick question is the salifert test better than nutrafin and what is the most accurate pH test kit ?If you're in the UK, do not buy the API kits, saliferts are much more accurate and can be bought for the same price online, the saliferts are much better than the API kits, they're more accurate, and more consistent.
ideally im looking for a way to test pH to the nearest point the liquid ones are ok but all i can tell from the readings is that the water is around pH 6.0Saliferts are the most accurate in that price band, and they're more accurate than nutrafins, all Ph test kits are of equal accuracy because they use the same reagents.
how can i tell if its 5.8 or 6.2 though is there another test as the nutrafin is quite hard to readNo, liquid reagents are best.
ill invest in a salifert and compare my resultsThe Salifert one will give a clearer reading, don't get too hung up on PH though, 5.8-6.2 isn't really a big gap.
