A favour to ask if you have a Hanna ULR PO4 reader and RO/DI

Oh right, someone was telling me about this the other day. Geez, you'd think they'd put something like that in the instructions.

That's actually not good news. It means my PO4 is way higher than I thought it was - both in the tank (which explains a lot) AND in my RO/DI (which probably explains why the tank is the way it is). Geeeeeez.
