    I've been battling algae for as long as I can remember even though nitrates and phosphates are undetectable with salifert and seachem test kits. I did a test now by scooping out some aragonite from the shallow sand bed and immediately noticed the smell, tested it and the phosphates are 0.2!!!

    Now, the whole sand bed needs to come out, what is the best way to do this without shocking the tank? Can I siphon sections at a time?

    That is a very dangerous thing you are doing, you should never stir your sand bed, those black area's are normal and will disappear after a while.
