Did you try shutting your skimmer down for part of the day? I know that Triton shows you in the green zone with phosphate, but for me .02 is too low. I need to keep mine around .08 for my corals to be happy.
Also, I found the Triton Detox to work well for me. You could try that to get rid of that AL and Cu. I previously had big problems from a high level of Al (280).
