Wp-40 / Wp-25 Observations

Recommended Posts

kbass   

For those who have not heard of the WP-40 or WP-25 powerhead pump, the pump is a Chinese inexpensive wavemaker (about $89 shipped). The WP-40 is somewhat comparable to the Vortech MP40, and the WP-25 is somewhere in between the MP40 and MP10. Both the WP-40 and WP-25 are controllable by either the controller they come with or by Apex with a quick mod.

These pumps can be purchased at: http://www.fish-street.com/wave_maker

My observations:

WP-40

I put a single WP-40 on my 72gal Bowfront in October 2013. The power of the pump was more than I expected. I was able to remove 3 of the 4 Koralia (2 1075 and 1 750). I left one 750 in to handle a dead spot caused by rock and over grown tank.

Initially, the pump created waves that could splash water out of my tank, and I had to turn it down a bit. The action was awesome and the corals all responded great to the new action. However, after about 2 months I noticed the action in the tank was not the same. The powerhead looked clean other than some coraline growing on it. I decided to take it out and check the impeller. It looked fine but felt a little slimy. So, I cleaned it. Wow! What a difference it made. The water was really moving again. The lesson learned??? Clean the pump once a month!

June 28, 2014...The pump is dead. For those interested in the math, the pump lasted approximately 8.5 months (Cost $10/month). I was not impressed...actually I was pretty pissed. I wrote Fish-Street about the problem. Within 6 hours I got a response. Eric offered no apologies, but told me the replacement parts were $25 (shipped) and sent me a paypal request for $25. Not exactly what I was looking for but hey let's see how the parts work. So, now I'm waiting for the parts. I will let you know how it goes.

The fix better last longer that 8 months, or the MP-40 is going to start looking better.

Wp-25

I have two WP-25s (total cost shipped: $158) in a 50 gal frag tank. Okay, maybe a little overkill. I pumps get cleaned monthly...they have the same issue as the WP-40. But really awesome action. These pumps have been running 7 months. I'm hoping for the best right now.

Overall:

1. These pumps are inexpensive.

2. Size of the pump...WP-40 is large. WP-25 is very reasonable for the power.

2. The action created by the pump is excellent, if cleaned regularly.

3. Durability is marginal at best. Based on the one pump failure I had after 8.5 months

4. Service from Fish-Street is pretty good...so far.

July 7 and the repair kit is here...wow that was quick. I was expecting parts and instructions...nope. It was the whole pump portion. Popped in the impeller and the front cover and I was up and running again. The pump is a newer model and it seems to have more power than my old one. I had to turn it down a bit, but really action.

So let's see how long it lasts.

Since Saltcrazy bumped this thread I will put my experience as well. I have two of the rw-8 models. Too much flow for my my 45 cube honestly. I also noticed the slow down after they slimed up a bit and honestly it worked in my situation because I did not need it full blast anyway.( I still cannot keep sand in front three inches of tank).

I bought two of these pumps about 16 months ago. I bought them cheapest on Amazon so no real warranty. I had one croak at about the 7-8 month mark. No explosion or leaking of anything in tank, just quit working. So I ordered another. First one is still going strong and I am actually using first controller on the pump I replaced and it has been going for three months or so I think.

In my opinion these pumps are quite good for the cost. I would not expect any tech support or warranty from manufacturer, nor did I expect it, especially buying through cheapest option at Amazon. Fish street seems to take pretty good care of purchaser from what I hear but the Amazon cost was significantly lower with free 2 day shipping.

Anyway I did buy again and will again in future. For the cost I do t feel can go wrong with what you get for the money.

I guess I can add a little. I ran 2 RW-15s in my 72 bowfront. These two pumps on full power were capable of splashing water out of the tank...so needless to say...lots of flow. These two pumps had been running for about a year before I shut down my tank. I did notice a slight drop in flow, but not near what I encountered with the WP model. I plan to run 2 RW-15s and 2 RW-8s in my 150 gal.

Jebao just released their newest models the PP4 8 15 etc. Supposedly better magnets. I was told by a vendor the only real reason the change the name is to combat warranty fraud. I went to elite today and the guys really took care of me. Paid a little more than amazon but got a year warranty. Put in an order for 2x rw-8s, 4 stage jebao doser, jebao dct600 return. All for under 325.00

I've been eyeballing the jebao returns. I see a few differences from "dc", "dct" and "dcs". But any recommendations? I'm making the assumption that because it is externally controlled I can over size and tune it back with less noise vs a bigger mag drive with a ball valve restricting it. I have a mag 5 running unrestricted now with "ok" noise. I'm wanting to step up my coral game so some serious flow seems like a good plan.

Lower power consumption, ramping power, can turn off to feed,and yespectrum you can completely control the pressure. They say it won't work for long distance travel, from a basement for example. The DC was the previous model, dct is the newer model with grey casing

I don't know how much you want to do this through your sump. Most of the flow turnover, especially associated with sps, should really be done with power heads so your mag 5 wide open may be appropriate.

Would a jump to DC be worth it just in terms of noise and features then? Also have a mag 7 on an old euro reef skimmer (8"x19") rated 350 gallon I think. Any more flow than a mag 7 be useful? Sorry for the thread hi-jack btw .

I run a mag 7 on my cube and have it restricted by a third to run a manifold which pushes water to my two reactors. It is plenty of flow though the tank. Don't have any experience with the do pumps but my mag is pretty well silent.

Mag 5, 7, 9.5, ect... Very dependable! Mine ran for 5 yrs no problems...and would fire back up if I plugged it in. However, I am going to try the DCT-12000 on my new tank. Reason...that's a good question...low voltage requirement in case we have a hurricane. Yeah...that sounds good.  If you decide to go with the DC pump, I would have a backup pump. Some people seem to have issues in a year or so, based on some reading I did.

I've run my mag for 10 years. It's the first pump I've owned since being in the hobby. Never had an issue with it and still runs today. That includes the times I've accidentally let my sump get to low and it drawing air a couple times. I won't replace it until I absolutely have to.

I would have a mag as a back up pump lol
