Aquarium bubbler for my AP

[Ellias]

H3llo folks! I just installed an aquarium air pump onto my AP solution. But my solution looks very dark brown/black. Does it still work, do i revive it somehow - any advice?

If it does not clear up and turn green with the air in a couple of days, add a bit HCl to convert the copper 1 chloride in copper 2 chloride.
Be sure to place the air pump above the jar to prevent a siphon effect if the pump fails.

This is actually the color after a week (I added bubbler today though) happen to know what this color is? I thought it was iron chloride at first, bit im not sure since there is a light yellow/green to it if i look at it with just a drop on a white spoon.

After a few days with bubbler it should become green again.
Or add a splash of HCl.

The color is the buildup of Cu⁺¹ ions. Adding the bubbler oxidizes the Cu⁺¹ to Cu⁺². The Cu⁺² will then dissolve more copper, creating Cu⁺¹ again, and that cycle repeats itself.
