outside. Remove the nut from the tank connector and the rubber washer and insert the rest of
the fitting as far as it will go through the larger of the two holes in the weir. Replace the rubber
washer and the nut and screw down firmly until hand-tight. Use the included screw tool from
PVC pipe to do so.
•
Some aquarists may want to apply silicon sealant to this pipework. This is not necessary
provided the fitting is inserted correctly and
Anthias
owners should be aware that this will
make subsequent removal of this fitting difficult.
•
Fitting the return pipe (25 mm) to the tank connector
•
Locate the 25 mm tank connector with the attached length of 25 mm pipe and hosetail. At the
hosetail end, remove the hosetail and nut taking care that any sealing rings are retained.
Remove the nut from the tank connector and the plastic seal. From inside the weir insert the
male end of the tank connector through the smaller of the two holes present in the base. Make
sure the rubber seal is present on the inside of the fitting. From below the aquarium replace
the plastic washer and then the nut and hand-tighten. Replace the hosetail making sure that its
rubber washer is correctly aligned.
•
Fitting the 40 mm strainer pipe
•
This has a round cap at one end and a number of straight openings along its length. Push this
into the weir end of the tank connector.
•
Carefully put the Bactoballs
into the chamber. When filled gently push down on the uppermost
balls to level them below the glass lip on the weir.

Fig. 1
:
The correct set up of the trickle plates, Bactoballs and 25 mm pipe in the weir of the
Anthias
aquarium. When operating, ensure the blue elbow is kept clean as this prevents back
siphoning of aquarium water that can occur during power cuts or when the Eco Runner 3700
circulating pump is turned off.
•
Place the trickle plates onto the glass lip inside the top of the weir. Use the plate with the
central hole on the left hand side of the aquarium as this fits directly over the 25 mm pipe
previously installed. The plates should fit flush and level.
•
Locate the remaining rigid 25 mm pipework consisting of a 90 degree elbow with anti-siphon
blue elbow attached and 45 degree elbow joined with two lengths of pipe. Insert the pipe
coming through the trickle plate inside the 90 degree elbow and point the pipe towards the left
hand wall of the aquarium.
