My parameters for the last month. I’ve had the tank up and running since August, so still fairly new. I’m now seeing some changes in alkalinity and I’m not sure why the calcium and mag are elevated…I would think it would go down with the LPS’s. Should I change the brand of salt? I believe the instant ocean reef crystals has added calcium and magnesium. Also, at what point would I need to address any of these parameters? Also, it’s due for a water change this weekend. Thanks for any input or advice!
