jabeo rw-4 for cadlight 8g

[ninhsavestheday]

Currently running the Hydro nano for the caddy. I want a pump that is more discrete and not an eye sore.

 

My question is the jebeo rw-4 smaller than a hydro nano?

[JavaJacketOC]

No, it's about the same size, maybe a little bigger. More controllable though.

[ninhsavestheday]

thanks java. how about the mp10?

MP10 would be less inside the tank but more outside the tank, also extremely controllable. I have one for sale

WP-10 is smaller than the RW-4. Here is a size comparison of wp10 and mp10: http://www.utahreefs.com/forum/forum_posts.asp?TID=68933&title=my-jebao-wp10-review

 

I still like MP10 better if you can afford it but they both move water.

I had a rw4 in my cad 8. I took it out it was too much flow. If you get the rw4 look into getting a controllable power supply. Fish street sells them for $10. Or you can find them online. Being able to Run the pump down to 12 volts gives you way more flexibility.

I run a 12v 500mA power supply and it works pretty well on reducing the flow rate for my 7 gallon.

That power supply isn't giving enough amperage for the pump, it'll be getting hot and could catch fire!

 

It's fine to mess with the voltage you supply a pump, worst that'll happen is it won't be enough to turn it or be to much and burn the pump out, but the way a pump works requires a certain amperage and while a pump will only draw the amperage it needs, so a supply with more amps than the pump uses is fine, if the power supply isn't rated to enough amps it gets hot as the pump is putting greater load on it than it's designed for.

These are a great inline fix for reducing the voltage to a Jebao pump.

Dirt cheap too, just plug and play, you can turn the voltage down too far with them and stop the pump working, but once you find your sweet spot your sorted.

I have to disagree with you. I haven't had any heat issues from the power supply nor the pump it's self and it's been running for a month or longer like that,at various speeds.

I would still stress to get a higher amperage power supply. Standard power supplies like that do not like to be loaded much more than 70-80% at most, and you're running it full bore (6 watts). The internal circuitry is not made to do that it will fail sooner rather than later, and when it comes to power supplies, their failure can mean fires. Unless you don't like where you're living right now, I'd get one that is rated at least 2A (which is a 24 watt power supply, the power consumption of the RW-4 is between 10 and 20 watts stock).

 

They are less than $7 with shipping on Amazon.

At the moment the pump is turned all the way down on the dial,On the first dot and on wave mode (first wave mode). I'll keep a eye out though.

thanks guys for the input.

Is the Jabeo wp-10 the same footprint (size) as the Hydor Koralia Nano?

No, but the RW-4 is only a small bit larger. I would not recommend the WP series at all.

[zsxking]

I have a cadlight 18G, and used both MP10 and RW-4 in it.

 

The MP10 runs at 40% purple mode. RW-4 was controlled by ReefAngle between 40~60%. Both are efficient in terms of creating flow.

 

When I was running RW-4, I put it in couple inch below filter intake, aim it to middle of the front glass. It's very unnoticable. In comparison, MP10 is in the side, 1/3 to the top, and 1/3 to the front (because of rock work). It's a lot more noticeable for sure.

 

The RW-4 only served less than a year then died. And it clogged more often than MP10 (which is never). But the end of its time, I kind of need to fully clean it every month to avoid reduced flow. But it's easier to setup because it can point the flow down and avoid pushing water over the edge. For MP10, it only goes straight and it's pushing water on the other side too close towards the top. Also it's very difficult to lower water line with cadlight's overflow, so that's a real struggle to me.

 

But overall, I like MP10 better. The laminar flow from one side to another seems better than chaotics flow, corals look better. But if RW-4 to be in the same place of MP10, it would stick quite longer into the tank. And its reliability is a important to me that I don't need to worry every time after water change if the pump will start up.

[jedimasterben]

zsxking, you sure have the RW-4 and not the WP-10? The RW series has intake grates that are like the MP10 and won't clog. The WP series have intake grates like Tunze pumps and need to be cleared often.

Anybody ever try trimming down the blades of an RW to down-rate the flow?

I still don't know why anyone would want to do that. It will make the motor off balance (even if only slightly) and will cause premature failure.

Yeah and with the questionable quality control on Jabeo thats the last thing you need. I also have all 3 pumps mentioned here (rw-4, wp-10 and mp-10) the Jabeos would probably be too much for a tank that small but if you have black background on the tank u probably wont notice to many smaller black pumps.

Running on a variable voltage supply you can cut flow to roughly 50-60% of nominal at 24v, so they can actually go on pretty dang small tanks.

This is a super tiny plastic prop, it's not something that needs to be precision balanced to begin with, and at that tiny diameter and relatively low rpms that it's turning I can't see how even a small imbalance is going to cause the motor to grenade. Think of the entire rotating mass, the prop, the shaft, the armature of the motor, the prop is a considerably small percentage of the rotational mass (probably on the order of 1%), a slight imbalance is not going to throw the whole thing off. These pumps can only go so slow, so using a variable voltage power supply might not be the answer, my Apex controlled RW4s just stop if I set them for any power below ~25% on the Apex.

Yes. It's technically not "clogged", but algae accumulated on the back half of the pump, inside the pump, and on the impeller. Also the motor thingy collect plenty of dirt too. The end result was flow noticeably weaker, and cleaning the pump increased the flow.

Got the rw-4 for my 70g which recently had Tunzes.

 

Its actually the same size as the Hydor nano. Can the 8g handle it? Yes in the lowest sending and only under the W1 mode. W2, even in the lowest setting, will blow water out of the tank.

I don't think that you can control the speed in W2 or Else modes. W2 goes in a sine wave from 30% to 100%.

My RW-15 only ramps to the maximum speed set with the little lights in ELSE mode. So if there's only one light on it just runs on a constant speed. I was sure that didn't do that with my 4's. I'm pretty sure they'd ramp all the way up and down in ELSE.

That doesn't sound correct, as the manual states that the entire RW line ignores any set speed in Else mode. Maybe you have a different/newer model of the controller?
