    I had an AM Ocean Runner 1700 pump left over from my Co2 injection experiments. Great Pumps REALLY...only problem is they are just a little louder than some people might appreciate, and that includes My Wife ! :(

    It takes alot to get a needle wheel pump with enough power to pump against a reasonable head pressure. This is where the O.R. pumps really shine, but be careful what you wish for. :eek: The tines on the needle wheel are flexible and of course it's designed to cavitate at high RPM. First time I fired one of these up you could not make me believe a pump of this quality should ever be quite so loud. I tried a different mounting plate, larger suction cups, anything to isolate the vibration. Then I discovered it was actually the tines themselves producing a harmonic and singing from the cavitation. After a few days breakin period it quieted down considerably, but still wouldn't pass muster with the Missus. The experimant itself worked a little too well. Producing more mist than any other configuration tested, but it burned through Co2 pretty quick, and in the end the noise was the deal breaker.

    I set up another mixing tank last week, and just happened to grab the O.R. 1700 for a circulating pump. Sure enough when I fired it up it produced an outstanding hum, but from the angle I was standing over the tank I finally witnessed the Ultra Sonic ripple on the surface of the water. I use Ultra Sonic cleaners for cleaning and polishing parts, and this mixing tank put even the best industrial units to shame ! :eek: I had the remnants of an old lumpy batch of Equilibrium setting around so I used it for my mix. This stuff is like concrete, and yet it went completely into solution in minutes right before my eyes. I've had this stuff take weeks to dissolve in my trickle filter even with a 685GPH flow rate, so it would be fair to say that it's an acid test for dissolved solids.

    The O.R. series of pumps may not be the most discrete series on the market, but if you need a high rate of injected mist, or a powerful efficient mixing pump I give it "The Pope's Blessing" As a mixing pump I wouldn't trade it for anything. I just don't run it when the wifes around. :D LOL. Prof M

    So that pump effectively turns the tank into an ultrasonic cleaner? Why don't you set up a tank somewhere where the noise won't be a problem, add about 3-4 watts per gallon, several plants and a few fish, run the lights about 12 hours a day. Then see if and how any algae develops. I keep wondering if ultrasonics would deter algae from doing well, and this would make an interesting way to see if that is even a possibility. Plus, it would show what the fish think of life with constant soothing massages.

    No, not a possum. Try a goldfish instead. The Endlers I have that keep lining up to try for the broad jump championship might work too.

    When feeding gas into pumps and venturi's:
    Use a small air stone to break the bubble up into smaller ones so they do not make nearly as much racket.
