Adequate SPS flow

I hope you plan on getting an LED dimmer for the wp25. It will blow your 20g alway. I have one wp25 on my 90 gallon and am very pleased with it. I haven't had to dial it back, but bought this incase i needed to:Ledwholesalers Inline PWM 12 Volt 2 Amp Dimmer for LED Strips with DC Jack, 3318 - Amazon.com

 

It has a controller on it that allows to dim the flow from 854-1717 gph.

I have about 1200 gph now.

 

Unless something has changed 2 months or so ago when i got mine, the controller only changes the speed in the W1 setting (standing wave that will probably overflow your tank on each impulse). You will probably want to run it in ELSE mode, which is random(ish), but has no speed control. The knob on the controller is a bit deceitful, it does not control speed/flow, but instead controls the TIME between impulses or speed changes depending on your set mode. The led dimmer in the link is plug and play and does not require you to splice any wires. In ELSE mode, this pump blows sand around in my 90 gallon if i am not careful. I think you will be very surprised by the flow this tiny powerhead puts out.

 

Oh, okay then. Thanks for the tip. This just plugs directly into the Jebao and controls speed in else mode, constant and wave?

 

How well does this work? I was considering this from fish-street fish street adustable power supply 12V to 24V
but amazon... and cheaper.....

 

yeah, you plug it between the wall plug and controller and it cuts the juice getting to the controller, thus cutting the amt transferred to the pump. Im not very good with electricity specifics, but this is a cheap solution that is easily removed if you don't like it or need it, but gives you more flexibility with the pump.

 

Does it work with all settings? Do you think
Test it on yours?

 

I haven't, but will try it here in an hour or so and will report back

 

Awesome. Thanks a bunch.

 

Ok, just tried it and it works pretty well. You cannot turn it down all the way, or your pump will just stop, but you can use about 70% of the range, not turning it below about 30%. I tried it on all modes with no issues. The plugs are compatible with the controller with no modification needed. The one from fish street would probably work just as well, if not better, but just costs more.
