    very new to this but what flow from the powerhead should i be getting, i come from the fresh water side and not use to the flow rate. when my power head is on it looks like it wants to rip the anemones off the rocks. is this too much? how do i gauge this

    @MarcVanJ sounds like your powerhead flow is a bit strong. Your corals should be able to flow from side to side without it being ripped out. How to determine which powerhead to choose you look at 10x to 20x your volume (if you are using 2 the combined flow rate should be the same as your requirement). By the way isn't your system a bit new for anemones, has your cycling process completed? Remember patience is key to this hobby.:thumbup:

    It depends on what you have, i am currently running about x 40 per hour for a mixed reef, if you have sps dominated some people run as high as 100

    Yes that's true, flow is dependent on what you have etc. plus with bigger systems you can go stronger than 10x or 20x but on a small nano (like @MarcVanJ has) that flexibility is small. The norm would be to start with from 10x to 20x, from there you can always add more if needed.

    Can you post a pic of the anemone, small and many sounds like they could be one of the pest anemones.

    More to flw than just turnover. Also depends on what you keeping, liverock placement, type of flow required, budget, etc
    Give us a breakdown of your tank specs and what you intend on keeping and well advise you on which pumps to get and how/where to place them.

    Those are Bali polyps you have there and not anemone looks like the flow is too strong for then thus they are closed. You want to have about 10-20 times turn over but you need to ensure that there is no dead spots where dirt can build up. Try the 3000l/h sun sun 101 direct it from one corner to the opposite corner in an upward direction. That should give you good flow for the size tank you have... Good luck:)

    Mate the direction of the flow is a biggy as well!
    It should break the surface or disperse on a wall to a degree before it creates current in the tank.
    If it is an actual power head, then get a small section of conduit and use a heat gun to direct it to get the right flow.
    What I normally do is heat one end and then fit it over the power heads out flow the run water over it each time to cool the pipe.
    Then I would heat the middle and bend it to suit what I want, then I heat the end and push in something like a paint scrapper and that spreads the end to give it a broad flow that is not invasive to much life and gives a huge softer current.
    That is if it is an actual power head and not a wave maker.

    ok cool thanx for the input. i rate my flow is too strong, when i turn it on it pushes the sand all over no matter what direction i put it in, im thinking of clipping one of the props in the powerhead or maybe trimming them to get less flow from the unit

    I wouldn't recommend doing that. By trimming or cutting one prop would cause a imbalance on the impeller thus causing your powerhead to wear inside and eventually fail.

    Could you give us a full tank shot so that we can see what powerhead you are using and it's positioning?
