I have been using strip tests but the ones that I have bought I don’t think are very reliable as the evaporation line shows near enough straight away. So I have bought some different tests - I have done one today and I am seeing some type of line but it has near enough no colour , I could see it within a few minutes…. Has anyone had this happen to them? Any advice ???can anyone see it too? ( the photos have gone blurry which doesn’t help 😭)
