Yes... that is high - very high. Most folks consider anything over 0.03 ppm something to be concerned about.

From your other thread, I see you're using tap water. That's where you're picking it up from. Flake food and overfeeding will introduce phosphates, but not at the levels you're seeing. Levels that high must be coming from your source water.
