What is a Flow Extender and what does it do?
The Flow Extender is a one inch long piece of pipe that fits in the 1" SCWD inlet, under the Drive Assembly. It was developed to provide a more concentrated flow of water to the Drive Impeller under low volume, high back pressure conditions. It also improves flow when using a 90 degree elbow entering the SCWD.

What if my Flow Extender fits loosely?
The Flow Extender was designed to be installed with a slight friction fit, as it is tapered from one end to the other. If it feels too loose, you can insert the non-chamfered end for a snugger fit. See the Supplement provided with your SCWD or review online.

How do I Install the Flow Extender?
The Flow Extender installation is quite simple. You remove the Drive Assembly, Install the Flow Extender inside the SCWD at the inlet, and replace the Drive Assembly. For step by step instructions, please refer to the supplement provide with the SCWD or review online.

Do I need flow accelerators with my 1" SCWD?
The 1" SCWD was designed to handle higher volumes of water. With the correct water pump, you should not need flow accelerators.

How can I get my 1" SCWD to work with Flow Accelerators, such as Eductors, Penductors, etc.?
When using Flow Accelerators you drastically reduce the volume of water going through the SCWD because the Flow Accelerators outlets are approximately inch in diameter. By installing a Flow Extender in the SCWD you will provide a more focused flow of water to the Drive allowing it to turn. Under higher pressure conditions, you may have to sleeve the Flow Extender to reduce its inside diameter. To do this, you can insert a piece of vinyl tubing or a smaller diameter pipe in the Flow Extender to provide an even more concentrated flow to the Impeller.

Do I need to use Teflon Tape when plumbing my 1" SCWD?
Yes. The Teflon Tape will make installing the fittings easier and improve the sealing of fittings to your SCWD inlet and outlets. By not using the Teflon Tape, the fittings could bind and damage the inlet and outlet ports of your SCWD and you may not get a good seal. Please follow the installation instructions in your Owner's Manual.

Do I need to remove the Swing Lock screws in order to remove the Drive Assembly?
No. The Swing Locks were designed to swing out of the way to allow access and removal of the Drive Assembly.

Can I use multiple 1" SCWD's?
Yes, provided the water volume requirements are met.

Can I change the switching speed of my 1" SCWD?
Currently, the switching speed is dependant on water volume going through the SCWD. The more water, the faster the switching. However, 3iQ Ventures is soon to release an accessory kit which utilizes a different Drive Assembly and Flow Extenders which will provide for a quicker switching response. It will also run under lower volume applications. It will allow the consumer several options depending on their set-up.

If my SCWD is not working correctly, do I need to tear down my system to have it fixed?
No. The 1" SCWD was designed so maintenance and adjustments could be made without having to remove the SCWD from the system. The Drive Assembly can be removed and replaced while the SCWD remains configured in your system.

How reliable is the 1" SCWD?
The 1" SCWD is designed and built to the highest standards and should provide years of flawless operation. Most calls we receive regarding problems with the 1" SCWD are attributed to water flow restrictions, Drive Assembly Installation, or set-up. Please refer to your Owners Manual for trouble shooting, as most problems are remedied quite easily.

Why should I put a SCWD in my Tank?
The SCWD is a revolutionary device. It is a mechanical wave maker, requiring no additional energy, made with demanding customers in mind. This innovative wave maker will stimulate coral growth, enhance fish health, and increases oxygenation in the water. The SCWD does this by creating similar movements as found in the ocean.

How does the SCWD work?
The SCWD takes water from your existing pump or filter and alternately switches water between the two outlet ports at varying intervals.

How will the SCWD help my aquarium?
The SCWD creates movements similar to those found in the ocean. These movements stimulate coral growth, enhance fish health, and increases oxygenation in the water.

How will the SCWD save energy?
The SCWD is a mechanical wave maker requiring no additional energy. Just hook it up to your existing aquarium set-up and watch it bring your tank to life.

How well does the SCWD hold up to hard water and heavy concentrations of calcium?
As mentioned SCWD has been field-tested for over 53000 hours of continuous use in a sustained reef environment where water conditions were at or above calcium levels of 400ppm. In addition, SCWD has been subjected to qualification testing, which included use of hard water and elevated calcium levels (1000ppm) that were sustained for six weeks. After one month the power head running the SCWD stopped working, and required cleaning. Two weeks later the same power head failed again, but SCWD continued to operate without incident.

What is the switching frequency/duration between the two outlet ports?
The SCWDs switching response is dependant on the amount of water volume running through the device. The more water, the faster the switching response.

Back to Top



Can SCWD be used inside the aquarium?
Absolutely. The SCWD can be mounted either internally or externally, depending on the desired results. The unit housing is completely sealed less the inlet and two outlets, so it may be hung outside the aquarium. The product materials are completely safe in both fresh and salt-water environments making it safe for installing inside the tank.

Will SCWD operate mounted upside down?
Yes. SCWD can run on any axis with no drop in performance.

How does small particulate and debris affect the SCWD?
Although not overly sensitive to the normal particulate and debris found in reef tank environments, it is strongly recommended that the water flowing through the SCWD is pre-filtered.

When I use my SCWD, I notice that the outlets dont completely restrict the flow of water
when in the closed position. Is there something wrong with my SCWD?

No. The SCWD was designed and manufactured to allow a certain amount of water to pass even when the outlet is in the closed position. Even with good filtration, there is always a chance that small sand granules or debris may find its way to the SCWD. This minimal clearance was designed into the product to allow for small particulate to pass through without impeding operation and reliability.

Can I use more than one SCWD for my tank?
Absolutely.

What are the inlet and outlet inside diameters?
The first model SCWDs ID for the inlets and outlets is one half inch.

What are the minimum and maximum pump ratings that can be used with the SCWD?
The SCWD can be run off a pump or power head at as low as 50 gallons per hour, and can be used with pump applications up to 1400 gallons and hour. Keep in mind that at fifty gallons an hour the switching response is very slow, and at 1400 gallons an hour the switching response is quite rapid.

What is the pressure rating for the SCWD?
The SCWD is guaranteed to withstand water pressures up to 5 PSI.

Back to Top



What are the approximate dimensions of the SCWD?
The dimensions of the SCWD are approximately 4.5" x 5".

Will the SCWD fit in an internal overflow box?
Whether it will fit will depend on the size of your overflow and the configuration of your outlet hoses.
