Just put in our fiberglass pool about a month ago. I got the Taylor 2006-k. The pool came with the general Chlorine and Ph test kit (oto?). Well I think my simple test kit is either old or defective. My taylor results are consistent with FC being 3.0 and Ph being 7.2. The simple test kit shows solid gold like an 8? and the Ph is through the roof as well. Thought I would use it inbetween the Taylor tests but seems like is way off. Anyone ever experience this? On a sidenote was at Leslies the other day for some Cya and saw they carried Taylor refills. The DPD they carried was in liquid form not the powder I have. Is there any difference between the powder and the liquid DPD? Thanks.
