That's what I was wondering, but after two months I thought levels should go down. I suggested he vacuum the sand.

Yes he has decreased the bioload. The tank used to be a predator tank with a shark, puffer, lion fish etc. Now he has about six fish including a regal tang, clown fish and a yellow tang. Corals number about the same or maybe as high as 10.
Phosphates as I have said were present in the old tank all along but with no algae bloom. Could it be his water? Levels aren't detected in 5 gal pail of newly mixed water, but could they be concentrated in 108 gals?
