periodic maintenance

I am a homeowner (electrical contractor). About 3 years ago I installed a Revolution 4 Burnham boiler which I am very happy with. However due to mild weather I am just getting ready to start it up and I noticed what looks like some black fungus (small amount) in thr tubing. Can you recommend a corrosion /anti fungus chemical. It is running on distilled water.

    Distilled Water:

    Are you using distilled water in your heating system?

    If so, why and who told you it was a good idea?

    What were their reasons for it?
