Very slick! Did you think of that yourself? Seems like it is probably a high energy solution, but... still very impressive

Thanks... yeah, it was an idea I came up with as far as the equipment I used, but really nothing too new as far as being used as a whole.

It looks like it works. I must say, I like the maxi-mods all except the noise they produce. I could definitely hear yours in the video.

Dang looks good!! How did you get it to oscillate? I've been wanting to do that with my tunzes.

I does look pretty neat. We saw it during the tour and everyone liked the idea. Just need to get the lovely and gracious Monica, aka planning & zoning, to buy off on it.

Of the 2 video clips, one is showing the stream in action and the other is of the mechs of the sweep and my fish room.

I watched the video, but what motor is that? Is it an osicallating fan you took apart?

It is just a clip on fan, upside down(mounted to the ceiling), with the fan and shroud removed. I then hung the fan directly over the center of the tank and drilled a hole through the brace(just over 3/4" for an easy, but not too roomy space that the 1/2" pvc cane rotate through w/o any drag). Then I attached a length of 1/2 pvc from the fan to the stream(in the tank at the desired depth... remember: too close to the surface if the water WILL result in sucking air), cut it in half and added a quick connect coupling(you may have to cut some length off of the 1/2 pvc due to the added length). I then attached both ends of the pvc to the bottom of the fan and the stream (trying to make it as strait and least off-centered as possible). Finally, I put all of these pieces together and place as desired in the tank, but you're not done... with everything in place and the PVC through the brace to the stream, mark the pvc that is through the brace 1/8" above the brace on the pvc( this is where I added a 1/2" pvc pipe coupling to sit directly at that line and above(will act as a stop and will not allow any more than a 1/8" drop if the overall length into the tank). Finally, with a small length of unpainted wire hanger, wrap a piece around the pvc between the the brace and the "stop" to act as a bushing and help to eliminate or decrease drag as well as to help the rotation to continue smoothly. Hopefully I've explained this well as this is pretty much what I've done and it seems to work really well... If you want to see this in person to get your own ideas, you're welcome to come on up. Just pm and we'll work something out.

That makes since. I just don't think my apartment complex would like me attaching stuff to the celing  . I've been trying to think of a way to do this that would be compact, but I haven't figured that out yet. I think an osciallting ph would make watermovement better ten fold.

You could consider a "brace" across the span of the tank to mount to and design similarly by just mounting to the brace... could be an eyesore though.

Who has the best selection on oscillating fans? I don't really care on price, because I want to get the smallest I can.

I got mine from Walmart... of course. However, I would suggest you pay the $$$ for a better built fan that can handle a little more drag on the gearing and possibly the ability to ocsillate at a slower pace. I tried to put an plug in light dimmer on the fan, but to no effect...

I've actually been trying to figure out how to do this for awhile. This is definetly the future of phs. It is only a matter of time before a company comes out with a decent ph that oscillates. I've tried designing an electric motor to oscillate back and forth, but to get it to do that is very difficult at least in a compact area. I need to take apart one of the cheap fans to see how they did it, because I know its not as simple as it seems.

Did you get any of your ideas from other forums? I'm curious because I'd like to read those if you did.
