Thanks Roy and Jesse, my tap water usually comes out around 7.2 or so; we get our water from the Spada Lake Reservoir up on Stevens Pass via the highland water district mainline. If I have time tomorrow I am going to run a sample of my aquarium water by AM Test tomorrow and get it officially tested; It'll be interesting to see if their results are different from our home API Kits? _______________________________________________ GSAS-Member mailing list GSAS-Member@thekrib.com http://lists.thekrib.com/mailman/listinfo/gsas-member
