I live in Seattle (Leschi) where the water is usually so soft and stable I do not regularly test for pH of the supply water. Whenever I have tested the Seattle water in the past it is always had a pH of 7.0. However...this Summer I and a fellow fish keeper who lives approx 6 mi. away (still in Seattle - different neighborhood) both have noticed that the pH has shifted to 7.4 - 7.6. Anyone else experiencing / notice this? Al _______________________________________________ GSAS-Member mailing list GSAS-Member@thekrib.com http://lists.thekrib.com/mailman/listinfo/gsas-member
