Ours is quite full of…..well,.. ..its hard to see the level of the black water even with a strong flashlight on the tanks top pointing down.
I have tried filling with clean water and rocking the boat. This did not work.
I added a quart of bleach plus some laundry detergent then filled with water and rocked the boat, let it sit for a few hours, rocked the boat more, emptied, refilled with fresh water 2x and its still very dirty. The water that comes out is pretty clean, its the tank inside sidewalls that remain dirty.
Basically I have crud on the inside walls of the holding tank.
Can anyone recommend a product to clean the inside of the holding tank?
