After a year I made my self a system for cleaning inside the tank.
Here in europe is hard to fiind a system .
I see in GM but is in USA. Is take more than 2 mounts to find the media 6x6 mm but I find.
The system is made from square 4x4xo.2cm Strong inaf to rol 2 tank 18 liter in the same time with 70 rpm.
Al axe with bearing, Electrical motor very strong 1,5 kw ,220v
Gear box from a winch system, with strong conection between the axe.
I made versatile is possible to tumbler a litlle tank in the same time with bigger.
And in the end a dimmer for low speed.
