[jeffvmd]

Got mine a couple of days ago.
Thanks again David for arranging this group buy for everyone.
Dry tested it and will try to find time to get this wet.

So I got one of these for my pump:

It works in lowering the flow a little bit, but not enough -- still to powerful for my tiny 16G

Have you tried it on your pump?

Have you tried it on your pump?

Yes, I have the dimmer plugged into the DC jack of the controller, and the power supply plugged into the dimmer.

The modulator/dimmer has an "off" setting that the knob clicks when it turns off. The dimmer is supposed to gradually change the power from 0% to 100%, which it would seem to do.

The controller, it seems, needs at least ~50% power to be turned on. So, on the dimmer, you have to turn the knob some distance past the "off" position in order to reach the power level where the controller turns on.

The dimmer works. When I turn the knob down I can feel that the strength of the pump decreases in all modes.

However, the minimum strength is still too strong for my personal tank; it still blew everything around more than I hoped (although it didn't rip my elegance out of the sand immediately).

if anyone wants to sell their 40 because its too powerful, ill take it off your hands

What does the knob control? Also I have two and one knob is much looser and turns easier then the other.

The knob controls the timing of the pulse.

So what settings is everyone using?

Please post the following:
- tank size
- model and number of pumps
- positioning
- settings

 

[ramon1181]

120 gal
W1 else mode
1 wp40
One side glass pointing straight
My fishes are having a hard time

 

[BaaMNYC]

110 tall' long

1 wp40
Middle of right glass pointed upward 35-40 degrees?

W2 with knob almost all the way to the right.

Oh yeah

45 gallon 24x18
1 Wp25
Left wall 3/4 up 1/4 from back wall
Pointing 40 degrees up toward opposite corner

W1 s1 knob in the middle

 

[Rob&Gab]

45 gallon tall

1 WP25

W1 S3

Left side in the back halfway of tank angled up towards the front.

knob all the way to the right

 

[TommyP]

55 gallon
1 wp25
left side of tank 3/4 up middle of glass
angled 30* or so...
w1 s3 knob all the way to the right

Was thinking about putting in one of my aqueon 250's on the right side of the tank to help disperse the flow a little because middle of the tank over to the right gets the returning flow (pushing it to the left) after it hits off the wall and my bubble is not happy ...

The knob controls the timing of the pulse.

So is the knob to the left slower pulsing and to the right faster?

I played with it but couldn't really tell a difference. (I am currently on else mode)

 

[TommyP]

It's the opposite. If you turn the dial to the left, it pulses quicker and shorter. If you turn the dial to the right, it's longer pulses.

Aim it up towards the water level (not too high! Just so you can get an idea. Or I stuck my hand in front of it to see how it worked.

On else mode, I believe the dial is useless.

120g
WP40
Side glass, towards back, with no obstructions
W1, Else

I took my MP20 out today after moving the WP so it wasn't obstructed by rock. I may or may not add it back in. I've also removed a Koralia 550 and 1050 (I think those were the numbers). As of tonight the WP40 is the only powerhead running.

Looks like we going to see a lot of used powerheads for sale :tongue1:

Ha ive got 4 koralia 750s and a red sea wavemaker. Replaced by two wp25s although I used my acIII instead of the wavemaker.

I switched my settings to w1 s2 and knob to the left I believe. We will see how that works out. Having internal weirs w external overflows rocks. Was worries about the wave at first as I have water level set to bottom of trim.

I'm not sure how it acts on else mode. I feel on the w modes to the right it pulses faster and the left slower.

opinions on wp 40

So now that you all have it, how does it compare to mp40?? is it worth it to get a wp40 for 100 or a used mp40 for 350?

Let's not get this thread closed. These comparisons always get heated. Thats my opinion.

I'm not the op but I'm finding this thread helpful.
