The main plumbing is 13 mm ID x 19 mm OD (1/2 inch x 3/4 inch)
Tygon tubing.
Place the intake and exhaust at the same height. Attach exhaust tubing
from the pump to the cage. Failure to place the exhaust tubing properly
can lead to acceleration of water in the plumbing, with resulting errors in
conductivity data.
Place the exhaust as far from the intake as possible, preferably in
diagonally opposing corners, so that exhaust water is not pulled into the
intake. Failure to place the exhaust away from the intake can lead to errors
in temperature data, because the pump transfers heat to the exhaust water.
Place a 13 mm (0.5 inch) long piece of 9.5 mm ID Tygon tubing at the
dissolved oxygen (DO) sensor intake and exhaust. Slide the larger
diameter Tygon tubing (13 mm ID) over the smaller diameter tubing to
provide tight seals.
If the system does not include a DO sensor, connect the tubing from the
conductivity cell directly to the Y-fitting.
