    I tested with new kits and these numbers were backed up by my lfs. Not sure what to do?

    Ph 7.8 measured in am
    Kh 19
    Ca 420
    Ammonia 0
    Nitrates and trites 0
    Phosphates 0
    Mg 1350
    Sg 1.024

    All I have been dosing for the last month or so is calcium, I've done 3 20. % water changes in the last month and no real changes, I use ro/di that has a new filter and 0 tds and instant ocean salt.

    You will want to get the dKH down through water changes to around 12. You will need to agitate the surface heavily to increase gas exchange. You most likely also need to air out the house thoroughly every day to lower the CO2 concentration in the air. pH is at its lowest in the AM normally.
