Install the Siphon Tubes
17
Siphon tubes slide over the standpipe in each fish-holding tank. As the system operates, water fills each tank and flows out the standpipes to the clarifier tanks
in large systems or biofiltration tanks in smaller systems. Siphon tubes keep fish from swimming into the standpipes while allowing water to pass through side
slots or side holes near the bottom of each tube. This system is equipped with two (2) types of siphon tubes; each serves a specific purpose as your fish grow.
Use the 112742 slotted siphon tube when fish are small. As fish grow and more waste is produced, replace the 112742 slotted tube or tubes with the 112743
tube with 1-1/8" holes. These holes help ensure a consistent water flow as the fish grow.
Install Siphon Tubes
Photo shows the standpipe as installed
inside the fish-holding tank. Air lines to
aerator stones are also shown.
1. Slide siphon tube down into tank and
over the standpipe.
Siphon tube with 1-1/8" holes is used for
larger fish.
Photo (left) shows a slotted
siphon tube for smaller fish.
2. Carefully seat siphon tube inside tank.
Length of tube must be above the water
level in the tank. Tube can be trimmed
to 1"-2" or so above tank if desired.
