The standard 6" mixing chamber tube for the Plank autofeeder.  This tube should extend about 4" underwater for best mixing action.  The platform is 1/2" thick, which means this standard length assumes approximately 1.5" between water level and tank rim.  Less than 1.5" water level difference is fine; the mixing still works well if the tube is a little bit deeper.

As of August 2023, All new mixing tubes now include a matching volute disk that friction fits inside.  Since tube batches may have inconsistent inner diameters, a new volute disk is often necessary.
