does the controller remember its last setting in the event of a power failure?
Steve - It appears to remember the setting if the lock mode is used. I unplugged the pump from the socket and even from the controller itself. When I waited a a few minutes and plugged it back it in it went back to W1 mode.
I was also thinking that you could put it on a timer via the apex and use it in conjunction with your other pumps rather than going thru the steps the others are going thru make it connect to the apex.
Steve - The pump is made cool. It reduces its flow once the light sensor detects its not bright enough. So it has a built in night mode. On my initial testing I did not have the pump in a place where the light contrast was enough to cause the sensor to work correctly. I am really impressed! This is day two of only one pump in the tank and its still stirring up stuff.
Henry, can you give us a better description of what the W2, W3 and Else modes are and what types of flow they create?
Steve - From my testing today here his a breakdown of the modes.
W1 - Wave mode where the pump completely comes to a stop and starts to create the wave.
W2 - Is not a wave mode it is a ramp up and ramp down profile.
W3 - Same thing is mode W2 but the ramping up and ramping down is a little longer.
Else - I think can be a real gem. It is random flow ramping up ramping down with varying intensity.
I still like W1 just because I look in the tank and feel like I'm in the ocean.
If there was a way to change the profiles thought the day that would be great but with what they already have its still fine.
Steve you are right, if these are as good as they seem(maybe like the LEDs) there might be an influx of vortech or Tunze pumps for sale. Not saying is is why but there seem to be a LOT more then normal vortech threads for sale. Now these pumps do have applications where only they will work. My tank will be eurobraced so I traded my Tunze to get vortechs.
but if you don't need a special set up these things could be the way to go

biecacka - My tank is Euro-braced as well
. I think Vortecs are cool since they make the tank look very clean and are like a status symbol. Lets face it this hobby is great to bring a friend over and say see what I have in my tank. Remember when the Australian Acans first came out if you did not have one in your tank you were not really "reefing". I think these pumps (Jebo) will be great for those looking for an affordable pump that produces great results. If they are long lasting they will fill that void that is missing in the market now. Like I mentioned I tried Vortecs as well but the noise they make after a while to me defeats the clean look especially since the wet or dry side seems to fail after a while. My single MP-10 makes more noise than 5 Tunze pumps. I all comes down to personal preference but just because a tank is euro-braced is not a reason to say it has to have Vortec pumps.

Wave line measurement
I turned the return pump off and WP-40 off as well. I gave the tank time to settle and then plugged the WP-40 back up. The wave it make spanned the lines below with the knob set at the second picture. The last video is is a front tank video...notice how hard the fish are swimming near the pump.

I am cutting it close on wave movement. I do not think I can increase the power any further for the wave intensity before I will be spilling water out my tank. It is going high enough that the wave goes above and below my current drains.
I shot another video or two but made the mistake of shooting it sideways...I will figure out if I can salvage the video or not.
