cleaning. The removable union on the return pipe allows
the pump to be removed for cleaning.
Pipe 2. Take the second pipe, which is pre-fitted with
an adjustable shut off valve. This should be fitted in the
centre hole especially if you are planning to connect
to a ClariSea filter, as the pipework is designed to be
ClariSea ready.
Remove the lower dog-leg section by unscrewing the
union on the valve. Take the knurled nut and tapered
washer, fit this to the straight upper section of the pipe
with the cup and thin part of the seal pointing upwards.
Slide the pipe through the tank connector so that the
valve is near the top of the cabinet and tighten enough
to hold the pipe in place but do not fully tighten at this
stage.
Pipe 3. Slide the straight pipe down through the tank
connector from above. From below slide on the tapered
washer and the knurled nut in the same orientation
as for the other pipes. Position the pipe up so that the
upper cut end is level with the glass of the weir section
without the overflow comb fitted. Tighten up the knurled
nut. This will provide the quietest running by reducing
trickle as the water flows into the weir box.
Installing the Filter Socks
If using the standard filter sock pre-filter option re-attach
the lower dog-leg section of pipework to the valve so
that the end of the pipe falls in the rear section behind
the filter socks. Make sure that the 'o' ring is still in
position in the valve union. Slide the pipe down so that
the bottom of this pipe is level with the bottom of the
emergency overflow pipe and then tighten the knurled
nut on the tank connector.
The aquarium comes as standard with two 4 inch,
200 micron filter socks to remove any fine particles
and will polish the water. Silencing is fitted to reduce any
water noise through the filters. The silencer sits above
the socks with the two pipes facing downwards into the
filters. As the filter socks block the water level will rise
and when fully blocked will overflow the filter chamber.
The socks can simply be removed and washed through
under the tap to clean them or can be replaced with
new ones which are available from your retailer.
Installing the optional ClariSea unit
If installing a Clarisea unit, remove the filter sock plate
and hang the fully assembled ClariSea on the rear sump
baffle in front of the pipework. The grey elbow at the back
should be facing upwards and in line with the middle pipe
coming down from the aquarium. It is best to position the
brackets for the ClariSea in the lowest fixing holes so that
the unit is sitting as high as possible. Insert the end of the
dog-leg section of pipework carefully into the elbow on
the ClariSea so that the union on the top of the pipe is in
line with the valve. Slide the pipe down to meet the dog-
leg section and re-attach the valve. Make sure that the 'o'
ring is still in position in the valve then tighten the knurled
nut on the tank connector. It is not necessary to glue this
section of pipework in to the ClariSea.
Go back and check the nuts on all 3 sets of pipework are
tightened up before filling the aquarium.
Initial testing of the pipework
When you fill the tank for the first time you can test that
the pipework and tank connectors do not leak by first
closing the valve on the syphon pipe and then filling the
overflow box only, rather than the main aquarium. Check
underneath for any weeping and, if necessary, tighten
up any loose connections. Working this way gives you
the option to remove the complete tank if needed to
correct any serious errors made during the pipework
installation process.
Assuming there are no leaks, fully open the syphon
valve and continue to fill the aquarium.
