    6 feet question

    Hello all,
    I have eight 5 inch pacu fishes which I house in a 6 feet tank. The tank has about 800 litres of water.
    I hope to purchase a pump head to create current.
    The reason why I'm doing this is because I believe that currents give my fishes exercise like their natural environment. Exercise also helps them to grow to their full potential.
    My question is, how powerful should the pump head be.
    I checked and found a range of pumps that have a turnover rate of 1000 - 4500 litres of water per hour.
    I want to get one that is powerful enuff but not too powerful that my fishes feel like they're training for the olympics.
    I was also considering to purchase a timer to have the pumphead on during certain times in the day like how they go to hunting and resting ground in the wild.
    Your xpert opinions are v much appreciated.

    sorry, pardon my ignorance, but y do u need a strong power head to create a stronger current for them to execrise? does it do anything to the fish? like healthy or something like that?

    Try using a eheim 1060, turnover rate is 38 l/min, u can fully submerger the pump and position the outlet ( attach to a control valve ) at any location u want the " current " to be. With the control valve u can adjust the " power ". This way ur pacus sure pass IPPT ! []

    aKoh,
    Currently I'm using a 1060 pump that is part of my 2260 cannister filter I'm using for the tank. It's already connected to a rainbar and I feel that the current is too tame. I think they need to go against at least one or two hours of stronger currents.

    Simon,
    Excercise helps them grow faster and develop better just like in the wild.

    Simon,
    Yes, I intend to add another powerhead. I'm trying to decide to power of that additional powerhead.

    Simon,

    it is true that many fish require good water movement to thrive.
    It is only natural for them. Pacus are very powerful fish.


    Dribee,

    For a 6 footer, i will use a pump that blows at at least 2000litres/hr blowing lengthwise along the tank. Your fish will be large enough in a very short time to be affected by the current. You can leave it on all the time.
    i will not recommend blowing width-wise as the water may flow/splash over the other end.

    i use powerheads extensively, and i use them for the sole purpose of creating currents and strong water movement (for tanks with large fish)

    Btw i hope you know that your tank cannot accomodate all of the pacus once they grow up.THey are very large and powerful fish, and startle easily- thus bang into tank walls easily.

    How thick is your tank glass? an adult pacu can break thinner glass walls.

    Whooops, Sorry for the jokes.

    Maybe I should try to put a stronger current in my tank also...

    dribee,

    just to add.
    from my experience, a powerhead of abt 2000-2500l/hr blowing in a 6ft tank will create a nice current but not overpowering.
    there will be some calm spots in the tank for them.
    i will put the powerhead abt 3/4 up the tank height and point the nozzle slanting a little upwards. if yours doesnt have a nozzle, you can place it a little nearer to the surface.

    if you feel that the current is too strong, you can always place large wood along the path of the flow to break it.

    you can on it 24 hrs a day

    Liquid,
    it all depends on what kind of setup you have

    if you like planted tanks, of coz you will not desire strong current in the water..
    perhaps thats why many of you find the idea of creating strong current amusing in the first place

    dribee, try disconnecting the rainbar and attach a 1/2" reducer to increase " the current ". BTW the reason why ur outlet flow rate is tame is bcoz of the internal canister filter stuffs. OR the other alternative is ( like I mentioned earlier )place another 1060 in ur tank to generate additional current ! ( man ! 2280 L/hr is no joke ! ) cheers !

    Guys,
    Thanks for the advice. I'll probably get a 2000-2500 litre per hour pump and blow it lengthwise. Put that on for about 6 hours a day. I'll post you the results as soon as I get the pump. Prob make my way down to Rainbow. Saw quite a good variation of pumps just a few days ago.

    Happy fishing!

    Isz,
    Ya, the pacus are pretty skittish, very much like piranahs. In fact, they are a close relative of the piranahs under the same species category.
    the thickness of the glass in my tank is about 15mm.
    Should be alright.
    Anyone has piranahs out there?
