I ordered March 5th and received the unit on today, the 20th. After my order was not shipped appropriately (they never shipped it and gave me another tracking code of another person's WP40), Eric (the seller) shipped my package on the 16th. Super fast shipping if they have shipped my order properly. The packaging was solid. I got everything I needed and had no problems assembling.
This WP40 basically looks like a tunze with less controlling features, but packs a more powerful punch. Its pretty big, measuring 6in length and 4in wide, but it looks fine in my 120g. My Koralia was slightly smaller.
I added the WP40 halfway down my 120g and aimed it slightly towards the floor. Turned it on and it worked beautifully. I did my weekly water change a few days ago and today I see the WP40 picking up all the stuff I probably missed when siphoning. I literally saw particles being suspended in the water. It was great until I noticed the noise.
If you watch the video, you can hear the noise. I do not like noise since I play my guitar next to my tank. The humming noise very noticeable, but not near as annoying as a properly set up MP40 running at 50%. I think it very similar noise to the tunze.
There are 6 flow mode:
H (high) - constant 3250gph flow
L (low) - constant ~1000gph flow
W1 - wave (pulsing) mode, there is a dial where you can adjust how long quick it pulse
W2 - not sure
W3 - not sure
Else - random ramp up/down and interval, great for random turbulance
My dial is set at 50% of W1, and I see a slight wave. Most people would aim the WP40 slightly toward the surface to create more of a wave and keep the high flow away from the corals. I will do the same when my 120g is converted into a reef within the next few weeks.
Performance is great, price is great, noise is decent, but durability is a big question mark. The WP40 can be controlled, but that is beyond what I need from this pump. If you are interested, then do your own research about how to do it. If this pump can last me at least 1 year, then I would call it a huge success. If you believe in chinese LED
, then you should believe in the WP40 as well.
