I defintiely don't have algae then. The discoloration has been on the floor since I noticed it over a month ago. My water has been clear the entire time. Any other thoughts? Metal? I tested my fill water, but not for metal.

The quick test for iron stains is a handful of Vitamin C tabs on a stained area for a few minutes. If the Vit. C lifts the stains, it's metal, probably iron.
Re: Is Algae Possible? CC=0
I have yet to try the vitamin C tabs on a stain; however, I was able to get my hands on the most recent water quality report for Philadelphia, PA.
Cl= 1.9-3.1 ppm
pH= 7.4 ppm
TA= 60 ppm
TH= 135 ppm
Lead= 90% of the water tested had less than 5.8 ppb
Copper= 90% of the water tested had less than .32 ppm
With those traces of lead and copper, is it possible to produce stains?

0.32 ppm of copper could stain; the lead will not.
