The SCWD (pronounced "squid") is a revolutionary device designed to provide alternating currents without the use of electricty. The SCWD mounts inline with 3/4" tubing, the two ports alternate the output, the bottom port is the input. A great alternative to expensive electronic ball valves. The SCWD will run on any pump with a minimum output of 50 GPH and a maximum output of 1400. The switching speed and current duration is dependent on the volume of water flowing through the SCWD. You can control the duration by controlling the flow going through the SCWD. Can be submersed for use with large power heads or used externally.
SCWD is regarded by industry experts as the most energy efficient wave-making product on the market. It replicates nature by generating alternating currents within a tank or pond. These currents stimulate coral, fish, and plant growth and keep other aquatic life healthy because of the tank or pond? increased water currents and oxygenation.
A great product with a full 90-day manufacturer`s warranty.

Converting psi to feet:
Multiply the psi by 2.31 to derive feet. example: 5 psi X 2.31 = 11.55 ft
Multiply the psi by 2.25 to derive feet. example: ex: 5 psi X 2.25 = 11.25 ft
The SCWD (pronounced “squid”) is a revolutionary device, designed and manufactured to provide years of reliable service. Clearly the most efficient wave maker on the market, coupled with unique and patent pending free-flow, low back-pressure features, this compact product is the best mechanical current generating device available on the market today.
This unit has been tested and is approved for use with pump applications not to exceed 1400 GPH and a maximum of 5 psi, with a minimum rating of no less than 50 GPH. To get the maximum benefit and safest operation from this product please carefully read and follow all instructions and recommendations contained in this manual.
READ AND FOLLOW ALL SAFETY INSTRUCTIONS - Even though this is not an electrical device, care should always be taken during installation, maintenance, or removal.
WARNING — To guard against injury, basic safety precautions should always be observed, including the following.
DANGER — To avoid possible electric shock, special care should be taken in the use of aquarium equipment.
1. It is important to avoid the possibility of an electrical aquarium accessory or receptacle from getting wet. Position the aquarium stand and tank to one side of a wall mounted receptacle to prevent water from dripping onto the receptacle or accessory plugs. A “drip loop” (shown in Diagram 1) should be arranged by the user for each power cord connecting an aquarium appliance to a receptacle. The “drip loop” is that part of the cord below the level of the receptacle, or connector if an extension cord is used, to prevent water from traveling along the cord and coming in contact with the receptacle.
DANGER - If the plug or receptacle does get wet, DON’T unplug the cord. Disconnect the fuse or circuit breaker that supplies power to the appliance. Then unplug and examine for presence of water in the receptacle.
2. Always unplug any accessory when not in use, before installing or removing parts, and cleaning.
3. Do not use any aquarium accessory for other than the intended use.
4. Do not install or store the SCWD or other accessories where they will be exposed to weather or temperature extremes.
Manufactured to the highest standards of quality and reliability, your new 3iQ Ventures LLC SCWD WaveMaker is designed to provide convenient, trouble-free operation. Careful attention to these instructions is the first step in ensuring that your wave maker will perform as intended.
Please Read All Instructions Completely Before Attempting to Install and Operate Your wave maker.
Special Note - Although there are many different ways to install your new SCWD, the following instructions reflect the preferred method of installation. In addition, even though your new SCWD is not overly sensitive to the normal particulate and debris found in aquarium systems, to ensure long life, water must be filtered prior to entering the SCWD.
a. Measure and cut two pieces of 3/4 inch (ID) hose for the two outlets. For best results, it is strongly recommended that both outlet hoses are cut equal in length, leaving the SCWD centered between the two outlets (ref. Diagram 1).
b. Measure and cut one piece of 3/4 inch (ID) hose that will be connected to the water pump, canister filter, or powerhead outlet at one end and the SCWD inlet on the other. It is recommended that an inline valve be installed between the water pump and the SCWD to allow for flow adjustment, and for ease of removal and cleaning of the outlet hoses if required.
c. Install one hose on each outlet of the SCWD by applying firm, but even pressure, until each hose is fully seated. It is recommended at this point that you install worm clamps for added protection against leaks and the possibility of the hose coming loose. Do not over-tighten the worm clamps.
d. Install the inlet hose using the same operations noted in 1.c., paying close attention not to exert too much force on the nipple.
e. Once all hoses are mounted and clamped, you are now ready to install the outlet elbows and nozzles on each end of the outlet hoses. By combining rigid elbows to form an angle over the aquarium side you can adjust the position of the outlet nozzles to give you the desired current affect. The configuration of the elbow is such that it will hang over the back of the tank on both sides like an upside down “U”, ref. Diagram 1. At this time, you should support the SCWD by mounting or hanging the SCWD from the back of your tank using a coat hanger (or suitable wire)
f. Connect the inlet hose with the inline valve to your pump, canister filter, or powerhead outlet. Be sure to use a worm clamp to avoid any potential leakage.
Congratulations! You are ready to begin operation of the #1 wave maker on the market.
Make certain the device (SCWD) is securely installed before operation.
a. Open the in-line valve between the water pump and your SCWD so that it is approximately half open. This is a precautionary step to prevent a full force surge to the SCWD when using some of the higher volume and pressure pumps.
b. Apply power to the water pump. Verify water outlets are expelling water and that there are no leaks at any of the connections. Verify that the device is switching water flow between the two outlets. Now open the in-line valve to desired flow.
Helpful Tip - Switching speed and current duration is dependent on the volume of water flowing through the SCWD. Higher volume pumps will naturally cause a quicker switching response than lower volume pumps. By adjusting your inline valve you will be able to regulate both the amount of flow and the switching speed.
a. Provided all instructions and tips are followed in the previous pages of this manual, your SCWD is designed and manufactured to be trouble-free. It is recommended, however, that you inspect your SCWD for general serviceability whenever maintaining your aquarium.
b. Inspect your SCWD and all hoses and their connections for leaks.
c. To assure proper water flow, inspect inlet hoses, outlet hoses, and nozzles for algae and slime build-up, and clean if required.
Helpful Tip - To prevent harm to fish and invertebrates, never use soap or detergents when cleaning your aquarium and supporting equipment.
a. There are very few things that can go wrong with the SCWD: If a problem should occur, please follow the recommendations for the specific conditions listed on the following page. Most problems are attributed to water that has not been sufficiently filtered prior to flowing through the SCWD. As mentioned earlier as a Special Note in section 1, Installation, water should always be filtered prior to entering the SCWD.
Symptom - Switching speed to slow
Remedy - Check pump for proper flow/pressure rating
Symptom - Switching speed inconsistent
Remedy - Check hoses for algae and slime obstructions.
Symptom - SCWD is noisy or stops abruptly, stops and starts sporadically
Remedy - Foreign debris is lodged in switching mechanism. Flush out unit to dislodge debris.
Verify prefiliter is installed and is not clogged or restricting flow.
