    I am thinking about buying a set of Hydor Koralias. Why a set? So i can have flow at 2 positions which is better then one (in my eyes).

    Options are:
    Hydor Koralia Nano 1: 900 liter/hour (small footprint of 2.4")
    Hydor Koralia Nano 2: 1600 liter/hour (small footprint of 2.4")
    Hydor Evolution 2800: 2800 liter/hour
    Hydor Evolution 4000: 4000 liter/hour


    So:
    - i am doubting between the first 3.
    - i will buy 2 of them.
    - right now, i can only mount them on the front window facing backwards (or with an angle) unless i do some modification on my tank.

    p.s. i have shrimp and don't want a massacre in my tank :)

    Tips?

    Hi Gilles,

    I used two koralia 2's (not sure what that translates to in the new evolution models) within my 37 gallon tank prior to upgrading the filter, for flow. They worked well. I found that the slots where the water is sucked in doesn't tend to be a problem with shrimp. My MP-10 slots were twice as wide and whacked some shrimp before I placed the foam screen on the outside. I also found that the "cover", which I don't think the evolution models have, reduced and narrowed the flow. I preferred to run mine without the end covers.

    I think it depends on your goals for the pumps. If you are trying to help water move through some thicker planting areas, I think the nanos would do well. If you are looking to improve general broad flow I would choose the evolutions. Maybe one evolution and one nano. That might give the most flexibility.

    How big is the tank?
