Are you tapped into Edmonton's water supply?  If so, we just had our tapwater tested by a reputable lab (actually the city's lab).  They found .01 ppm of ortho-phosphate, which means there's next to no PO4 in our tapwater.  I
can do water changes to my heart's content.

We've been using the Aquarium Pharmaceuticals PO4 test kits for the past few months (the only one I can find locally) and have concluded they're _extremely_ unreliable.  Since I'm now assured that no PO4 is in our tapwater,
I'm now going to assume it's all being generated from inside our tank.

Additional CO2 will reduce the pH in your tank withour resorting to chemicals.

Both of these products are available locally (at DAD's FishRoom), so you can save on shipping costs just by driving to Old Strathcona.
