anyone tried to using Jebo WP40?

Dennis where can I buy a low pass filter? Can't seem to find one.

Or it may just be easier to make one? Looks very straight forward.

I expect Roberto will be making an interface for the RA, but if you want something sooner you will have to build it. The RC low pass filter should be a single resistor and capacitor. The resistor goes inline with the RA PWM signal. The capacitor goes between ground and the PWM signal after the resistor. The only variables are what values to use. I don't have a pump to test with, so I can't say what works well, but I am sure Roberto can tell you what he used.

Dennis I came to this conclusion just a bit ago after digging a tad. I already asked Roberto for his values and will most likely go grab the required parts tomorrow.

Thanks for all the help so far.
 
Whatever you guys are talking about are way over my head!:confused: I sense a break through is imminent in terms of controlling the WP40 by an external controller. Please keep it simple for us lowly folks who don't understand the differences between PWM, 0-10v, 0-5v, low pass filters, Arduino....etc. Pictures and diagrams of how it is done will be greatly appreciated.:lol2:

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.

Crap that's the one I bought... That's dumb it needs a fan in the adapter.

That's what I thought at first too, but too much sand was blowing around. I didnt notice it for the first week or so. I started getting little mounds all over tank. I find 20v is prefect for my tank.

It didn't take a week with mine. I woke up this morning to bare sand-less patches and dunes all over my tank. The water is fairly cloudy as well even with the filter sock. I have spent all day "raking" the sand back the way I want it and playing with the settings and angle of the unit to keep it from blowing sand at all. I really regret using sugar fine sand when I set this tank up.

I haven't rec'd the power supply yet. I ordered it and the WP40 on the same day and the power supply was supposedly shipping from within the US, so how come I still haven't rec'd the power supply?

The sand bed probably needed a good "hurricane" since it had a lot of areas I wasn't able to reach to clean regularly. Hopefully after my latest changes it will settle down. If not then hopefully I'll get the power supply in the near future.
 
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.

Thanks. I am starting to question the wave putting too much stress on the rimless though???

Nope as long as it was professionally built I can guarantee you it was designed to put up with that kind of flow and wave action only thing that thing could effect, is your stand and as long as its sturdy you've got nothing to worry about.
 
Well my tank is a ReefSavvy so I know it's well built and the stand has extra 2x4 bracing inside the stand so I should be good there as well. It's not like I have a huge wave it's only about 1/2"
 
I still havent ordered one yet. I think I'm going to wait a month and if everyone's is still running if they areIll go ahead and pull the triggerfish. Im cautious because it would be a huge pain in the wrasse to wind up with a broken pump less than a month after using it. I have been able to talk a couple of people at my local fish club into buying it and they are willing to let me come over and see it in action.
 
The wave action will put stress on the tank. If it seems too much it may be. I'm planning on using the random mode as not to create pattern that could lead to a rocking motion.

Take a look at video and let me know if you think it's too much

The random flow setting Elos even at the lowest setting and lowest Volts is WAY too much flow for my tank. My softies and LPS are blowing around like a tornado.
 
This is 2 WP-40s at 24v in a 125 gallon. In no way would I run this for an extended period of time. The water almost comes out of the tank and the fish look like they're getting beaten around.

15v-18v works great for two pumps though in any mode.
