    Iv got a 450l 900mmx750mmx750mm cube. Now how much current is enough for my fish to be happy? Dont want too much so that they stuck to the glass.....but also not too lil that they look suspended. :lol:

    How many powerheads.....or how much flow is needed on average to keep the tank happy?

    IMO it has much more to do with the types of coral that you intend keeping rather than the fish. What sort of system are you trying to achieve with this tank ?

    Well put Neil. What corals do you want to keep? I find that healthy fish can handle a lot of current.

    Hi Wetty. Clever positioning of pumps in order to obtain 0/minimal detritus settlement will not really have an effect on having your fish stuck to the glass.

    50 times turnover will be fine. Aiming powerheads behind rock work etc...

    Fifty times for an SPS reef, maybe forty or thirty for softies and LPS's

    and even if you dont have corrals you still want it in the region of 30 times vollume per hour to try minimise the detritus build up.......ESPECIALY in a Fish only system where you may be pushing the bioload of a tank and feeding heavily. You want to get the stuff from out the rock, into the water collum and over the overflow to be sprted by the skimmer or sump. Without sufficient flow in the tank you will get a build up of detritus and the associated deteriation in water quality.

    PS, rather talk of flow (chaotic in particular) than current as this could mean electrical current as much as moving water.

    And quality flow is far better than too much flow :)

    Not necessarily Tony. If you have look at Jacques system which is mainly LPS and Softies, He has an insane turnover, more than some of us SPS keepers have. Lets wait for him to pop in to give us an accurate turnover.
