DIY Instructions
Thank you for choosing the
Synergy Reef Overflow
. Please note that this is a Do-It-Yourself project and can be
installed in either glass or acrylic aquariums. Always keep in mind that working with power tools, glass and acrylic
have inherent dangers, including personal injury, electrocution, accidental death, or cracked glass, so please be careful
and wear gloves, shoes, pants, eye protection, etc… If you have any questions or concerns, please email us at
. Prior to installation, be sure that you have everything you will need to complete the
installation. This includes, but is not limited to:
Aquarium, either glass or acrylic, if it’s glass please make sure the panel you are going to drill is NOT
TEMPERED! If you are uncertain about this then STOP and please contact the tank manufacturer. If you
attempt to drill a tempered panel, it will shatter.
Cordless drill with adjustable clutch. We recommend the use of a cordless drill to avoid electrocution, as water
needs to be applied over the hole saw during drilling. The clutch will limit torque transfer to the glass,
reducing the chances of cracking the glass. Always set your torque to the lowest level on the drill, patience is a
virtue when drilling glass.
Drilling template (included with the Synergy Reef Overflow Kit).
Tape measure, to determine mounting location.
Permeant Marker or wax pencil to mark mounting location.
Spring clamps and/or double sided tape to hold the template in place while you drill.
Water source. Spray bottle, garden hose, bucket, etc…
Correct Holesaw:
-
60mm is used for both our 16” Overflow and 20” Overflow.
-
For glass you will need to purchase a diamond coated holesaw
-
For acrylic you will need a standard holesaw with teeth sold at most home improvement stores.

Drilling and Installing:
1.
Determine your desired water level. We find with typical applications within our recommended flow rates the
water level in our boxes will rise ¼” to ½” (depending on GPH of flow) from the bottom of the teeth slots. So
mark the drilling template about 1” below the top and this is a rough guide as to where you water level will be.
Use this measurement to determine where you would like to place your internal overflow box. Once you have
your desired water level determined you can measure and mark how far down the holes will be from the top of
the tank using our template. We recommend at least 1.5 to 2 inches from the water level to the top of the tank
for rimless aquariums. Tanks with bracing, the water level will be higher.
