I tested for phosphate and low range levels are undetectable, according to my test kit (aquarium solutions) they are zero.

If i had corraline covered rock the red algae would hardly be noticeable with only a small amount on the sand and glass. But on the bare rock it starts to grow and gets long and hairy....scrubbing rock every few weeks is not an option.

Hmmm guess guess bare rock in sw tank will allways be a problem.
