I boiled my carbon yesterday before using it and a lot of crap came out of it. I didn't test to see if phosphates had leached out but I assume they may have. In any case, I will always boil carbon first. After boiling, I rinsed it in RO and I was impressed with how little the RO water washed out of the carbon, it was relatively clean.

Hmm, I just soak it overnight now, but may go to boiling. Did you boil it in the microwave?
