    Duncans are low light, deep water corals. Try changing the bulb to blue light.

    hi nathan
    judging by reflection on water it seems to be either twin t5 lighting or a single PC lamp

    also the water surface seems very calm to me, so I feel that either light or flow are the key issues here , if your certain your parameter tests are all in order

    they could of been stung by that torch you have in there. thats what it looks like. or maybe a parasite. and they could be very stressed out.

    there are 4 bulbs in the light , but they are 2 joined together , 1 is blue and 1 is white , do you recomend putting another blue in do u ?

    and for flow would you recommend it be a stronger flow?... the store where i purchase have the exact same setup and they're tank is pretty stagnent

    Yes and Yes
    Try for at least 10x flow

    Maybe start by having your return bar in the water pointing to the front of the tank. And buy a small circulation pump.

    I check weekly
    magnesium
    kh
    ph
    calcium
    nitrates
    nitrites
    salinity
    I dose strontium and iodide and potassium in very small amounts.
    Duncans should do well under most lighting ie...pcs,t5s
