Hi All,

I have made a stupid mistake that, when I tried to change the acid in the right bath, I drained the bath before checking if there is enough acid to fill it up. And unfortunately, there is absolutely none sulfuric acid storage in the cabinet at all, so I have to end up filling the right bath with DI water.

I am truly sorry for being so careless and I apologize for any inconvenience!

Best,
Pengyu

Hi All,

I have filled the right H2SO4/H2O2 bath up with acid, thanks to John for restocking the sulfuric acid.

Best,
