Mu*u-sama Protein Skimmer [Kaido Kappa Large] Operation Confirmed

All parts are included except for the mat filter.
The wood stone was purchased new, used for less than a week, washed with water, and then stored.
Regarding the dirt, there are some white marks around the air intake of the dirty water tank due to slight modifications made to adjust the air volume (all modified parts have been removed). However, I have confirmed that these marks do not significantly affect its performance compared to a new one.
Please consider this point before purchasing if you are particular about appearance.

I am selling this because I switched to a venturi system and no longer need it.
