Plumbing the Overflow to your Sump.

So you now have your aquarium drilled and the overflow installed. If not, go back and watch this video on How to Drill You Aquarium for the Shadow Overflow.

Now you need to get the overflow plumbed into you sump. Here are some questions you first need to ask yourself to plumb it properly.

1. How many gallons per hour (GPH) will my tank be running?

   – 2500 GPH is the Maximum flow rate for 1 Shadow Overflow. You can use 1 Shadow Overflow on any size aquarium that will be running anything up to 2500 GPH. If you have a larger aquarium and need more flow, just install more Shadow Overflows!

2. How many Shadow Overflows am I running?

   – 1, 2, 3? This will indicate how many drain lines you will need. 1 Overflow will require 3 drain lines. 2 Overflows will need 6 drains. While some can be combined, it depends on each setup.

3. How many drain bulkheads does my current sump have?

   – The Shadow Overflow requires a minimum of 3 drain lines up to 1.5″ each for the quietest operation. Some sumps only have 2 drain line ports. You will need to run the 3rd drain into your skimmer section.

4. What size are your sumps drain lines?

   – We recommend 3 x 1.5″ drain lines on the sump for flow rates over 1500 GPH. If your sump only has 1″ drains installed on it, you can use it. You will need to reduce the drain lines down on the overflow to 1″, this does reduce your maximum flow rate to 1500 GPH.

5. How long will my drain lines be? Short runs under the stand or long runs to a basement or remote sump.

   – The best way to plumb the Shadow drains is with short runs. While long runs will work, you will need to do your research and make sure the drains are all draining down, with no sections going up.

6. Where do I install the gate valve?

   – The gate valve should be installed on the primary drain line. So what ever drain port you choose to use as the primary (any of the 3 will work perfectly fine) will have the gate valve installed on it. You need to install the gate valve where you can access it easily and still be able to see the rear box of the overflow. This way you can tune the rear box properly. We DO NOT recommend installing the gate valve in a remote location. This makes it very difficult to fine tune the overflow.

Items needed to plumb the Shadow overflow Rear box:

• PVC Cement, We prefer RectorSeal Mike 425L (Found on Amazon)
• PVC Cutters or Saw
• Measuring Tape
• 3 Pieces of 1.5″ PVC Pipe Min of 4″ in Length
• 3 1.5″ Unions
• 1 x 1.5″ Gate Valve

What Glue can I use to install the pipes on the rear box of the Shadow V1?

• Use only these following solvents on the Rear Box fittings:
  • We recommend using Rectorseal® Mike 425L  as the best solvent. If that cannot be found then Standard Clear Medium PVC Cement (Sold at local hardware stores) will also work, but may cause crazing on the rear box fittings. This crazing will not affect the fittings.
• DO NOT USE the any of the following as they can damage the Rear Box:
  • ABS TO PVC Transition cement (Teal Colored glue)
  • Purple PVC Primer. This can damage the plastics. Only use clear cleaner made for ABS plastics if needed.

**Remove from tank prior to gluing pipes to avoid damage.
**DO NOT Force Dry fitted pieces into the bottom of the rear box. This could possibly damage the overflow. Only push PVC with a chamfered edge and with PVC
Cement into the holes. ***

1. Attach 3 short pieces (approx. 4”) of 1.5” PVC to the bottom of the rear box with above mentioned solvents.
2. We recommend you using Rectorseal Mike 425L on outside of the rear box when gluing the PVC pipes to it. We have found that this Cement will work the best, but extreme care needs to be used when gluing to make sure the pipes do not slip out or the ports get damaged from too much force. If the proper amount of glue is used it will not take any force to push the pipes into the ports. See figure A.2 Below:
3. We recommend that you attach 3 x 1.5” Unions to the 3 pieces you just glued into the bottom of the rear box. This will allow for easy removal of the overflow if needed in the future or for moving the overflow to another tank later.

Installation Instructions:
Thank you for choosing the Synergy Reef Shadow® 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 contact us.

Prior to installation, be sure that you have everything you will need to complete the installation. This includes, but is not limited to the following:

1. 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.
2. 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 (clutch) to the
   lowest level on the drill and adjust accordingly, patience is a virtue when drilling glass.
   Drilling template (included with the Synergy Reef Overflow Kit and you can download it here
   https://synergyreef.com/Manuals/Synergy_Reef_Drilling_Template_16_Shadow.pdf).
3. Tape measure, to determine mounting location.
4. Permanent Marker or wax pencil to mark mounting location.
5. Spring clamps and/or double sided tape to hold the template in place while you drill.
6. Water source. Spray bottle, garden hose, bucket, etc…
7.  Correct Holesaw:
   We recommend a 63 mm Diamond Holesaw for best results A 65mm Diamond Holesaw or 2.5” can also be used for both our 16” Overflow and 20” Overflow.
   – For glass you will need to purchase a diamond coated holesaw bit
   – For acrylic you will need a standard holesaw bit with teeth sold at most home improvement stores.
8. Synergy Reef Shadow Overflow Kit.
9. 1.5” PVC for internal box. We have pre cut Internal pipe kits available here in many colors.

Standard Clear Medium PVC Cement (Sold at local hardware stores) ***DO NOT USE ABS TO PVC Transition cement (Teal Colored glue)!!***

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 your 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 a minimum 1.5 to 2 inches from the water level to the top of the tank for rimless aquariums. Tanks with plastic bracing or euro bracing,
   the water level will be higher (depending on where the trim is located). Leave 1/8” to ¼” Clearance from trim to top of template so there is no
   interference with the trim and front box.
2. Now locate the drilling template where you have determined you need to drill the hole(s). Note that the template is the same outline as the actual
   Front Overflow Box. Make sure the template is in the CORRECT UP orientation. Manually align the template on the inside of the aquarium and
   MARK the holes with your marker.
3. After marking the holes locations, use the Rear Overflow Box and align it to the circles you just drew on the aquarium. If the rear box aligns with
   the holes and is not hitting the rear plastic trim on trimmed tanks (make sure to test with the lid on the rear box as well), then you are ready to mount
   the template and drill. Mount the drilling template on the outside of the aquarium. You can use duct tape to mount the template, although we do
   recommend using spring clamps to hold it in place. DO NOT use screw type clamps, these can cause too much localized stress and crack your
   glass!
4. Make sure to protect the opposite panel and position a bucket or reservoir to catch the plug when it drills through. Also if placing a bucket on the
   glass, protect the glass from the bucket by placing a piece of paper towel and/or clean cardboard so that the bucket doesn’t scratch the tank.
5. Ideally you will use a cordless drill with an adjustable clutch that can be set very light. This will prevent extra force on the glass should you bind the
   bit during drilling. It is now time to start drilling!! Pour some regular old water in the template hole to cool and lubricate the hole saw, you will want
   to keep the bit wet through the whole drilling process. The provided template will keep your hole saw in place. Water will channel thru the template.
   This is normal.
6. After drilling for a bit you should be able to remove the hole saw from the template and see a groove starting in the glass. Once you see this groove
   you may want to remove the drilling template; it has served its purpose. Be sure to start both holes before removing the template.
7. Remember to keep the hole-saw wet through the process for cooling and lubrication. As you get near to the end of drilling the hole you will see the
   water start to leak through, this is the sign that you are close. At this point you will want to use very light pressure and patience to minimize chip out
   on the opposite side. However, some chips is normal and likely so don’t worry about them as the gasket will cover and seal them.
8. Once you drill both holes, clean up the drilling mess and dry the aquarium and proceed to install the boxes.
9. Remove the locking nuts from the front overflow box. Place 1 gasket on each of the bulkheads on the front overflow box and mount the Shadow
   Overflow by inserting the bulkheads through the holes you just drilled from the inside of the tank, this gasket will be between the front overflow box
   and the tank. Get another gasket and put it over each bulkhead on the outside of the tank. This gasket will be between the tank and the external box.
   Insert the external box through the bulkheads and secure it in place with the 2 locking nuts your removed earlier and hand tighten. Over tightening
   the bulkheads can cause the gaskets to leak. See figure A.2 on next page.
10. Remove the rear box from your tank and your overflow is now ready to plumb any way you choose. We recommend using 3 small pieces of 1.5”
    PVC (4” Pre Cut kits are available here) and connection these to the rear box and attaching unions to each. This makes it easier to remove or attach the pipes if needed for
    maintenance.
11. Make sure to support the external plumbing properly to avoid any weight pulling down on the overflow rear box. The overflow was
    NOT designed to have the plumbing hanging from it. We sell a few different pipe hanging clips here:  1.5″ Clic Clip or 1.5″ Cobra ClipPlumbing options for inside of the rear box: DO NOT GLUE any of the inside parts together.
    INSIDE OF THE REAR BOX:
    —-DO NOT GLUE THESE TOGETHER, Dry fitting it all that is needed.—
    1. First Cut 1.5” PVC into 3 pieces. 1 x 6.25”, 1 x 2.75”, 1 x 3.5”
    2. You will need to attach the following parts:
    a) 2.75” PVC Pipe to Synergy U-Pipe elbow (included in kit)
    b) 3.5” PVC Pipe to Synergy U-Pipe elbow
    3. Connect both of the U-Pipe assemblies you just made into any of the holes inside of the rear box assembly.
    4. Connect the 6.25” PVC Pipe into the last open hole inside of the rear box assembly. This is your Emergency drain.
    5. See FIGURE A.1 for finished assembly.

    OUTSIDE OF THE REAR BOX: *****Remove from tank prior to gluing pipes to avoid damage.
    **DO NOT USE ABS TO PVC Transition Cement!**
    **DO NOT Force Dry fitted pieces into the bottom of the rear box. This could possibly damage the overflow. Only push PVC with a cleaned edge and with PVC
    Cement into the holes. ***
    1. Attach 3 short pieces (approx. 4”) of 1.5” PVC to the bottom of the rear box with Medium Clear PVC Cement.
    2. We recommend you using Medium Clear PVC Cement on outside of the rear box when gluing the PVC pipes to it. We have found that Standard
    PVC Cement will work the best, but extreme care needs to be used when gluing to make sure the pipes do not slip out or the ports get damaged from too much force. If the proper amount of glue is used it will not take any force to push the pipes into the ports.
    3. Attach 1.5” Unions to the 3 pieces you just glued into the bottom of the rear box. This will allow for easy removal of the overflow if needed.
