Bob,Chuck, Thank you for your help.Very much appreciated. I have a 32g water reservoir for water changes.I run a powerhead with a attached peat filled quickfilter constantly.I measured that pH this morning at 8.1, way to high.I used to get the pH down to 7.0 with the peat filtration. I talked to the water supplier this morning.They told me that they shoot for a pH of 7.6 to 8.2 the pH is adjusted with lime.It used to be 7.4 pH without any changes for years. I'll be getting a year old water analysis, too. This screws me up quite a bit. I'll guess my next big investment will be a Ro unit.
