Assembly Instructions for the Sutherland Scapable Sandfall Kit

Sutherland Scapable Sandfall Assembly Instructions

Model SF12012060A

Notes before beginning

A.  While you are doing the assembly of the kit you will also need to be adding the stone or wood around the unit. 

B.  This unit has been tested with PetCo Imaginarium® white sand, which is the whitest sand we have found and has a grain size of approximately 1 mm.  Other sands with a similar or larger grain size should work as well.  If the sand is too fine it will not fall properly.  

C.  If the PVC tubing is kinked it may be worthwhile to boil it for five to ten minutes to restore the proper shape to the tubing prior to starting.

      The Sutherland Scapable Sandfall Kit is very flexible and can be assembled in a variety of different ways to fit your aquarium and scaping concept.  

There are two types of connections.

Type ONE - Hose to Fitting

  A 5/8" OD hose can simply be inserted to the nozzle, the reservoir, and at least one end of every adapter.  The hose should slide in more than 1/2" and will stay secure during assembly.  After assembly, the connection will also be held together by the scaping that you add around the components.  This connection helps to maximize the sandflow and has been proven to be reliable. 


Type TWO - Adapter to Nozzle/Reservoir - Some adapters have a smaller end with a notch on it.  The nozzle and reservoir have a hole with a groove.  Simply align the notch and the groove, insert the adapter and once fully inserted, rotate as needed.

Step 1.  Reservoir Assembly - Assemble four suction cups to the bottom of the reservoir.  This helps to insure the reservoir is level when installed.

Step 2.  Attach Pump  - The input side of the reservoir is the side with the Aquavista Aquatics Logo and this is where the pump should be connected to.  Use either the included hose or any 1/2" ID hose with a 5/8" OD.  You may also use one of the RA adapters that is included in order to route the hose as needed.

Step 3.  Configure Nozzle - The nozzle can be attached directly to the 5/8" diameter hose, but it is more typical to use one of the two included right angle adapters.  Attach either standard RA Nozzle adapter to attach nozzle to back of aquarium, or use the 45 degree adapter if installing the nozzle in the corner.  Attach suction cup.

Step 4.  Connect Output - Connect Hose and Right Angle connectors as needed to Place Reservoir in tank and connect pump with either 1” PVC or ¾” tubing or 1” PVC.  Make sure the reservoir is level from front to back.  Do not rest a heavy rock on the outflow side of the reservoir as this will tilt the reservoir in the wrong direction and affect sand flow.

Step 5.  Assemble Nozzle to Reservoir - Final assembly of the Nozzle to the output of the reservoir you just assembled.  There are many options, but here is a typical configuration


Step 6.  Fill tank with water and turn on pump.  Then add sand to reservoir to desired level.  It is recommended to plan on doing this before scaping anything other than the sandFall in order to see how the sand flows with the sandfall scaping in place.  You will likely have to drain the tank and fix a few things on the scape and then fill with water again, possibly repeating a couple of time to get your desired look and to make sure the sand all flows into the reservoir properly.
