Guess what! UPGRADE TIME

[mrhasan]

Got myself a new toy



And resulted in this:



Too much flow and the sands started blowing around (although being 1.0-2.0mm grains). Had to turn it to L mode and can't use the fancies because of the sand storm. And fishes seem to struggle too. But I am very impressed with build quality. The magnet is freaking strong too! So much for the brand-lovers......

Will try to find a variable DC unit to control the speed. That should solve the problem

let me know where you end up getting one as i have been holding off on dropping one of these in my tank because of their power and have been to lazy to look for myself where to find the variable control

You should check out the huge thread on Reef Central. They are making all sorts of advances on how to make adjustable power. Looks like they have a good working idea using some sort of rheostat.

Almost 100 pages for you to read through lol -

I added a couple of those tunze pumps to supplement my mp40's and am very impressed. I almost like them better than the correct pumps because they're far more quiet. I'm considering replacing all my vortex pumps with the tunze pumps.

What Tunze's? I was unaware we were talking about Tunze's lol.

Yah I started going through those but might take a couple of days :P Too much fights and stuffs between brand lovers and budget reefers :P Some are using 18v adapters but might not be good for a pump rated @ 24v. So they are now working on modifying the PWN module; no words on it yet other than controlling with reef angel.

Those things are soooooooo history if this pump can even live for a year

All you need to set the voltage to the pump to slow it down is a selectable output voltage transformer available from electronic supply places like active tech or radio shack. The controller is the true problem as it will be designed for a certain voltage and likely wont operate properly on less voltage but it should be fine to run it and the pump on 18v possibly even less. I run model trains that use /24v motors as low as 6v for short runs and about 15v for hours at a time. Your amp draw will climb with the lower voltage.

Yah that's where the problem is I guess. The adapter gives 2.5A to the controller so if it goes above that, it might not be good isinit?

Im not overly confident, but I think they might have figured it out:
