Default I need help with measuring PO4
Looking for someone in the Calgary area to help me...

I need someone who has a Merck or D-D PO4 test kit, or a Hanna PO4 photometer to help me test my PO4 levels.

Here's my issue ... I HAVE the Hanna PO4 photometer but I suspect it is defective as I cannot get any readings with any degree of consistency. Ie. the numbers are all over the map. For example, I just took three readings on the same tank water and got 0.12, 0.04, 0.26.

Just to eliminate the possibility of user error, I need someone who can help me establish what my water PO4 really is.

Anyone? Please?
