Plank Replacement Standard Mixing Tube

Plank Replacement Standard Mixing Tube

$ 8.00
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.
