    I am sure I have seen a thread discussing this topic but cant seem to find it so here goes. How much flow should I have in my tank. My system is 200l and I currently have 2 x 3800l/h Seio prop P1000, 1 x 2000l/h Seio prop P530 and 1 x (4000l/h) Boyu WM1 and of course my return Which I have dialed right down so not that much flow from that. Is there a formula to work out if I have sufficient flow or perhaps too much ?

    Flow is quite dependant on your inmates.

    Also quality more than quantity ;)

    How do you define QUALITY flow ?

    Quality IMO could be defined by random, turbulent, non-linear flow...

    Normally the brand - Vortech is the "Ferrari" of pumps/flow.

    Tunze is the "BMW"

    and Seio the "Toyota"

    If you get into the actual mechanics/science of these little machines, you're see how one vortech can do the same job as 3 or 4 Seios

    Brent - your flow is more than ample. You add all the total litres per hour of the pumps up, and then divide it by the total litres of your display tank. That's how you determine how much water flow you have.
    It seems that you may have +-50 times water turnover....

    In my opinion, having more pumps pointed in different directions, would create more chaotic/random/turbulent water flow.

    The only thing that I would still like to do, is to have a "wavemaker" type thing where pumps are switched on and off at random, causing an ebb-and-flow surge effect.....

    How many times would be classed as enough versus too much ? If I work it out then I have 68 times turnover.

    This depends on the corals you are keeping. SPS you can go past 100x but some softies and LPS would die with this amount of flow.

    Brent - soft corals also adapt very well to high flow. The only soft corals that I have found that does not like too high water flow, are corrallimorphs mushrooms.

    Usually, your long polyped/tentacled LPS corals, prefer medium to low flow. Meaning that you can still have high flow in the upper regions of your tank, as long as your water flow is not to strong at the bottom of the tank....

    I have +-92 times water flow in my 2 metre reef tank. BUT, even with that amount of water flow, I do have areas in my tank which has low to medium flow.... and the hammer corals flourish in these areas!

    No problems Brent..... It's about time that you add some corals, hey! ;)

    I would like to start and suggest the following:
    - zoanthids is ALWAYS a great choice - and you get some of the most amazing colorations
    - leather corals is always a winner - you get quite a few types
    - IF you have found that you do indeed have some low flow spots in your tank, then you can have a look at the following LPS corals:
    = trachyphyllia (brain corals)
    = frogspawn
    = hammer corals
    = torch corals
    - IF you want to perhaps try an "easy" and hardier SPS coral type, you can have a look at some of the following:
    = montipora digidata
    = montipora capricornis
    = hydnopora

    For very low flow areas, corrallimorphs mushrooms, elephant ears, rhodactis mushroom corals, ricordia mushroom corals - are all good choices for low/very-low flow areas..... and you get some amazing colorations of these as well.....

    Please stay away from the colorful gorgonia corals, and "strawberry treecorals" (dendronephtya species)..... And unless you don't mind constant feeding, please don't buy a sun-coral....

    Would you suggest a controller for the Seio's to give more random flow ?

    Is it the Seio controller? If it is I am definately interested. Just need to find out if the Seio props work on it. PM me what you want for it please.

    Brent - yes - the SEIO props do indeed work with the controllers. They are indeed an awesome addition - and I am more than sure that you won't be sorry.....

    Thanks Jacques. I was just a little concerned as an the write up of the controller it lists the specific Seio's that work on the unit and the Props were not mentioned.
