OK, I'm back.
I have a Salifert PO4 Profi Test.
The phosphate tested at 0.25 or under. It was kinda hard to tell, but it was *defintely* no higher than 0.25.
Although ostrow's comment about the algae being efficient consumers of the phosphate makes sense too!
Maybe when I go back into the LFS tomorrow, I'll bring a sample of water...
