anyone tried to using Jebo WP40?

Ron, that's amazing flow you are showing in your 180g with just one WP40. That was my initial concern and now it is confirmed that you cannot adjust the speed of the pump other than time/interval. It is strange that we are complaining the pump is too strong. It is definitely not a wavemaker for small tank. I like your idea of covering the backside to restrict the flow. May be you can make a circular piece of plastic or acrylic that you can rotate and adjust to partially cover the backside. I ordered two WP40 for my 92 g corner tank. From what you said probably one is enough. I may have one to sell:)

In your 92g tank you are going to want speed control!

Great review of the pump. Looks like you got your money worth as long as the thing holds up for a couple of years. Nice tank!

So far o good, now I just need to wait a couple of years! Thanks for the compliment, it's been great fun.

Ron, do you have a Kill-a-watt meter or some way to measure the wattage used in running the pump? From the adapter label, the output said 24V at 2.5amp which means around 60W. I suspect the actual wattage consumed is much lower in wave mode or in L mode.

48 watts in 'H' mode and 8w in 'L' mode. and it goes from 8 to 0 and back to 8 over and over. In the wave modes it just goes up and down between 0 and 48w.
 
I am not knowledgeable in electronics but a couple ideas that I came across or stole from another forum to control the speed of the pump:

1. Use of a variable DC power supply with voltages like 8, 10, 12, 14, 16, 18, 20, 22, and 24V. The lower voltage should lower the speed of the pump.

2. Since the light sensor reduces the speed of the pump, replace the light sensor with a variable resistor or one that can be programmed thru some kind of controller or computer to control speed. This is a brilliant idea if it works!

How about some kind of a reostat between the controller and the pump? I know there are DC motor speed controllers. We just need the right one.

I like idea 2 as well... if somebody can get it to work? How do we get ahold of Jebao to get a schematic of the controller? You could be selling an accessory to the wp line of pumps!
 
Would a few of these be worth buying for a 5' L x 3' W x 4' T (400 gallons) tank ? I was planning on running a closed loop with a hammer head but these look appealing. It will be a SPS reef mixed.
 
I'm kind of excited about the flow. My 36 will probably take a beating but this may help suspend detritus and eliminate dead spots. The tank is bb so blowing sand is no worries!
 
I think what would work in this case is a PWM module. I have a 24v one that was for a led project. It would allow you to control with an apex or rheostat. It would hook up between the controller and the pump.

I'm interested in getting one of these, but the WP40 may be too much for my 80g tank.

Ron, maybe you can help me understand what these modes do and the options available with them.

Modes:

H: Constant stream at 13000L
L: Constant stream at 4300L

W1: makes standing waves with wavelength adjustable?
W2 and W3: ?
W3 reef stream mode: ?
Feed mode: stops pump for 10 mins

The description on the website is a little hard for me to fully understand. Any help clarifying would be appreciated.

For right now, I'd say buy one and see what you think. The hum/whir that it makes is weird. We can sit at the dinning room table and at 5-6' we can hardly hear it. But at my computer in the living room 15-18' away I can hear it. It's not loud, but then my wife will tell you I half deaf (but it's the high pitched stuff I can't hear). I think 2 WP40's could be enough. And if not, buy a third or get a WP25 when they come out and put it on the back glass? So understand, I'm not recommending them, I'm saying they'll move your water. You have to decide if they work for you and if the sound is accepable.

Floyd, please share more info. I do 120v stuff all the time, but DC and small motors are very new for me. What do I need to look for in a PWM module? Do I need to match voltage, amps, watts? And what does PWM mean anyway?:lmao:

Ron, maybe you can help me understand what these modes do and the options available with them.

Modes:
H: Constant stream at 13000L 4500gph steady flow
L: Constant stream at 4300L 1500gph steady flow
W1: makes standing waves with wavelength adjustable? Very short pulse and can create some huge waves. Pulse length can be varied, but they are all short.
W2 and W3: Longer pulse that is more of a ramp up and then ramp down. Not much for waves, but varies the stream flow. I think W3 is even longer cycles than W2.
Feed mode: stops pump for 10 mins And restarts on it's own

Hope that helps.

Thanks for the video funny how cats always wants to get in the middle of things.

My cat could care less about my tank...

Simon SKL's idea is a great one. That light sensory or CDS cell is just providing variable resistance depending on the amount of light it sees. If it has any markings on it indicating its resistance levels, a potentiometer could replace it and a simple turn of a knob would then control the pump speed. All you have to do is figure out the min/max resistance of the CDS cell and then mimic that in a potentiometer. Heck, you could probably just wing it and try a few potentiometers (they are cheap) and report back.

It would work!

This is a pretty cool pump, neat find!

I wonder if the video in Photobucket can be viewed by multiple people at the same time. I didn't have any trouble viewing it. May be wait a few min and try again.
 
Seems like the wp40 would be a lil much for my 105 sps tank build 48x24x21 would you guys agree. Think I'm gonna wait for the wp25

At full power... the only way it works as sold, I'd agree. But if we find an easy fix to controlling the power to the pump... who knows.
