Plank Mixing Tube

Custom length tubes for The Plank
These can be used for sump installations or other custom installs. 

For optimal mixing and dispersal of food (without it going over the overflow), the tube should extend ~4" beneath the water.

To measure for an in-sump installation:

If the water level in your sump is 7” below the rim, you'll need a tube that's 11 inches long. Here's how we determined this:

• Mixing depth: 4” (how far down in the water the tube needs to reach)
• Distance from rim to water level: 7”

Adding them together, you get 4” + 7” = 11” for the length of the tube needed.

Note

• OEM Length for Plank v3.5 and earlier is 6"
• OEM Length for Plank v3.6 is 5"
