How hard to care for SPS coral compared to LPS.

  1. Never had SPS before.

    well
    the PH is reasonably constant and is fine
    the nitrogen cycle paramters are also good

    but those Calcium and DKH readings are fluctuating to much IMO
    and you are not showing a Magnesium level - and thats key to keeping the Calcium and DKH stable

    add one and the other falls out - if you dont have the Magnesium level to support them both

    a DKH of 8 is fine IMO you just have to keep it at 8 -
    6 is a problem as its below NSW levels and many people have reported issues with SPS corals and a DKH that low often comes up as a potential cause

    a calcium level between 380 and 450 is fine
    pick a number and try and keep it at that number
    its better to dose and compensate for 10ppm reduction on a daily basis then to allow it to fall to base line and then raise it back up again

    with SPS - think Stability Provides Success (Thank you Tatted4ever)

    the more constant you can keep those key parameters the happier those corals will be

    additional - aim for an SG of 1.025 - 1.026 as thats closer to NSW level and helps with achieving the targets on Mag, Cal and DKH
