    I have 125 reef for last 6 years. Im pretty happy with all but slow grow SPS pick 1. Any special requirements for them? All others grow fast even some other SPS but some like pick 1 no at all. Still have a good color. Maybe low ALK around 6 dKH or PH 8.0? Good flow from 4 power heads. MG 1280, Phosfate 0 Nitrate 5. Please let me know. Thanks.

    Yes, ALK and MG are both low which can cause slow or halted growth with more sensitive Acros. You will want to raise them slowly over a few days though, not all at once. Also, what is your CA level?

    It is a dry heat, yeah right !
    Bring your mag up to 1350 and then retest the alk and adjust to at least 7.

    Yip, that's what I was going to say too. I wouldn't trust a Ca reading of 420 when my Mg was under 1300...

    SPS......slow....grow......that sounds about right to me. Those words go together.

    How long have you had these frags? It can take months to acclimate and begin to grow.
