Congratulations on your purchase of the Reef Glass Nano Skimmer.  We know 

you will be pleased with the results. 
 

Parts Included: 

1.

 

Glass Skimmer Body

:  Made with high quality Pyrex glass.  It has a 

simple and practical straight shape so you can remove the air stone 
from the top without having to unmount the skimmer. 

2.

 

Acrylic Mount

:  Versatile mount allows you to install the skimmer on 

most rimless and rimmed tanks. 

3.

 

Mount Screw

:  Can be screwed on the back of the mount for rimless 

tanks and on the front of the mount for rimmed tanks. 

4.

 

Rubber Stopper

:  Has an air inlet hole and a waste drain hole.  The air 

valve must be placed into the air inlet hole and the elbow connector 
must be inserted into the waste drain hole. 

5.

 

Limewood  Airstone

:    Made  of  high  quality  limewood,  produces 

microbubbles that trap the waste that is subsequently drained to a 

waste container of your choice. 

6.

 

Rigid Acrylic Tube

:  One end must be inserted into the air inlet hole 

on the bottom of the rubber stopper.  The other end has a flexible 
connector  for  connecting  the  limewood  airstone.    Comes  pre-
assembled for your convenience. 

7.

 

O-Ring

:  Holds the glass skimmer on the acrylic mount and can be 

adjusted to change the positioning of the skimmer. 

8.

 

Air Valve

:  Must be inserted into the air inlet hole on the top of the 

rubber stopper.  Use it to adjust air flow to the limewood airstone.  

9.

 

Drain Elbow connector

:  One end must be inserted into the waste 

drain hole on the rubber stopper.  Connect a length of flexible tubing 
to the other end of the elbow of sufficient length to reach the waste 
container. 

10.

 

Flexible

 

tubing

:  4’ of flexible tubing is included. 

11.

 

Straight tubing

 

connector

:  Can be optionally inserted into a hole on 

the cap of your waste container or to connect airline tubing directly 
to the air inlet if you prefer to use your own in-line air valve. 

Parts Needed: 

 

Air Pump

:  We recommend AP-3 Danner, Tetra Whisper 10, Whisper 

20  or  similar  pump.    Note  that  limewood  airstones  require  more 
pressure than regular airstones. 

 

Waste Container

:  Can be as simple as a used water bottle. Air must 

be able to exit the container at all times for proper operation.  We 
recommend  that  you  leave  the  waste  container  uncapped.  If  you 
decide to place a cap, then you must drill 2 holes on the cap, one for 

inserting the included straight tubing connector and another one to 
permit  the  free  flow  of  air.  The  hole  for  the  connector  is 
approximately 5/32” (drill bit size).
