Ni,
There are black residues on the reservoir walls and on the suface of the electrolytes in the reservoir.
However, the electrolyte seems clean but a slight yellowish
The distilled water in the bubbler is clean
Do I have a problem or is this normal at the start of a new reactor (only 250 km) ?
Last question, when the electrolyte level down in my tank, I might add only distilled water or a mixture of my electrolyte?
Thanks in advance
Your help is appreciate
