    Which air pumps is better, Pondmaster or Hakko?

    I am going to get a air pump for my new koi pond. I am still wondering between these two air pumps. Could you all please give me some feedbacks in term of capacity, duration, ....My pond is 3,000gal. I have about 30 koi and they are about same sizes, 6 inches. Thanks in advance.

    I think most will find the Hakko to be a better pump overall. But as far as price goes, the pondmaster might be a decent option. I've got two pondmaster (I believe they're made by Dolphin) and they work great. Not as much air for the same rating as a Hakko, but reliable. Just buy bigger than you need.

    Of course, you could get the Hakko for free if you traded about 20 of your fish for it which is a win win!! (I think you're overstocked)

    Good luck

    You could try using Hi-blow. I got mine from Eastern.

    yep, you are around 3 time over stocked if you had any plans to keep them past infancy. Koi can easily grow over 24" each and some in the 30+" range. That is why we tend to say the minimum per koi is 250 gallons...with more being better.

    As for pumping air into the pond system, a good rule of thumb is 40l for each 1000gallons. So with 3000gallons, a pump in the 100-120 liter range should be OK. Personally I like the Dolphin AV-150. My experience with them is that they deliver ~100L.

    Haven't heard that rule of thumb for air. I'm quite a bit over... but good to know! Thanks.

    It comes from Koi 2 Kichi by Peter Waddington. The suggestion was 40 liters was for 1,000UK gallons which converts to 1,200US gallons. So if you stay with 40L for 1,000US gallons you will have a gracious plenty.

    Coming from you was more than good enough for me! But thanks for the reference!

    Hi,

    In my opinion the original Hi-Blow pumps from Japan are the best airpumps available. I use 2 HI-BLow 80's. 1 for my filter and 1 for the pond (i have airdomes on my 2 bottomdrains)

    Rgrds,

    Wouter

    I've found Medo pumps to be very reliant and more efficient. They use less amps for the same flow as Hakko.

    One of the problems is we have not stated the criteria for what is "best".

    Is it any one or a combination of:
    - availablity (you can easily find them and any needed parts)
    - capital cost for pump (and maybe replacement diaphrams or pistongs)
    - operational expense (watts consumed)
    - performance (liters per minute at what backpressure...such as 1 meter, 2 meters, 3meters)
    - reliability (frequency of repairs)


    Depending how you weight each of the above criteria...you will definitely get a different brand and model.
