AB+ black stuff

[mrhammy]

I dose 20ml of AB+ every day. It can only last a week without refrigeration, so every Sunday is fill day. Clean the reservoir and add 140 ml. Today, when measuring my AB+ I saw black flecks in the fluid... anyone see this, and is it ok?

Mine would turn black as it was souring from not being refrigerated. Now I dose that manually
