    I have 2 SPS frags both Montipora Digitata. They seem to be growing but they never extend their polyps. I have had one for about 7 weeks and the other for 6. My water parameters are all good
    Ammonia 0.0
    Nitrites 0.0
    Nitrates <10
    CA 420
    PH 8.3
    dKH 10.8
    SG 1.024
    Temp 79-82
    They are under 2x250W 6500K MH with 2x110 03Actinics in a 75G tank. I have adjust my PH so that flow is strong but not crazy on both.

    Any suggestions would be great

    For whatever reason, your digis don't need to extend their polyps when your looking, their polyps are used for photosynthesis, food capture and defense. The LAST thing a coral will expend energy on is growth...if you have good growth, then the coral is healthy and you should not worry about it too much. FWIW, I've been there, in my tank I have several digis, some extend their polyps and some don't.
