anyone tried to using Jebo WP40?

Wouldn't it also stand a good chance of making the pump last longer with a voltage regulator and a lower power setting?

I have a 120 gallon tank, 48" long 24" wide. 25" high

Should I order one or two of these?

Or should I order the 25's when they come out to go with the 40 ?
 
Another observation. The 120w variable power supply from Amazon linked earlier in this thread has a built in fan. The fan annoyingly ramps up and down in correlation to the pump's speed. For those of us who are more sensitive to noise, that power supply will be another, albeit small, source of noise.

I have since switched back to the original power supply. The flow in W2 mode with the wave interval set at the lowest setting does not over power my 48x20x20 tank. It all depends on the location of the pump and your aquascape.
 
Got mine today and started playing with it. DAMN this thing moved a LOT of water and is a LOT bigger than I expected. Might be too much for my 105 even with it dialed back. What mode are you all getting the back and forth motion with?

If the 25s were available right now, I would have gotten two of them for my tank. Two should work well in yours as well. Two pumps should allow better coverage and minimize dead spots in the tank.

As the 25s were not available and I didn't want to wait for something that did not have a definite release date, I bought one of the 40s. At this moment I don't feel the need to add another pump as it works just fine for me in my setup.

If you don't want to wait and aren't too concern about spending more money, you can get two 40s and run them at a lower voltage with two variable power supply.

If you want to get your new pump now, get one 40 with a way to decrease the voltage and you can add another 25 down the line. I don't believe there is any shipping discount if you buy more than one pump at the same time, so it's not like you'll waste money on shipping twice.

W1 is best for the back and forth motion. Play with the knob until you get it dialed in how you like it.

My tank has similar dimensions to yours. Dialing the knob just a little shy of the midpoint gives me a nice back and forth, wave like motion.
 
OK, Roberto from Reefangel has determined how this pump is being controlled. The VA line is using a 0 to +5V Analog signal to control the speed. Similar to the 0 to+10V method of control only limited to +5V.

So those of you with Analog dimming should be able to interface directly without the controller but you would have to make sure you did not exceed 5V.

That kind of screws everyone with PWM, an arduino, or an Apex with 0-10v. No wonder I couldn't get it working at all with pwm. Analog dimming usually requires a + and - wire, so I wonder how it could be hooked up.

I want to keep the wave modes on the controller working, so it seems that the 0-10v PWM module Floyd has is the only option.
 
Not really. You can generate an analog signal using a PWM output by using a low pass filter. In fact after hearing this news I went and looked at the photo of the controller board that Ron posted again and it is using a low pass filter to convert PWM to analog for the signal it is providing.

For the Apex, just do not exceed 50% (5V) and you will be fine.

For the Arduino, use a low pass filter.

For the Reefangel with a 10V PWM signal, both would apply, use a low pass filter and do not exceed 50% (5V).

However you should use a meter to double check what % the cut off (5V) actually is.

A video is coming....
My tank is a 30"x30"x31" cube and one pump is doing a fine job moving water. My only complaint is that it is a bit loud this morning. It was reasonably quiet yesterday. I hope mine quiets down like Ron's did over a week or two. Other than that no complaints.
 
So far mine is SUPER quite and making a nice little wave action on W1. I am just not sure it providing enough "flow" in the tank. I have never had a Wave maker so I don't know how to compare the "wave action" to actual "flow".

Previously I had 2 Korilla 750's on each side in the rear facing at each of other meeting in the back middle of the tank on 24/7. In the back top corners I had 2 Korilla 1400s pointing across the surface of the water meeting at the top middle front of the tank randomly alternating.

Right not I have removed the 1400s and installed the WP40 (slowed down to 15v)at the top back side shooting across the top middle of the tank towards the other side. Like I said I love the wave action it looks so much more natural. I am just not sure there is enough "flow" now.

Any tips or thoughts appreciated.

Roberto over at reefangel has the pump hooked up via pwm or analog!!! He had to use a low pass filter and a custom harness he made.
