I have instant ocean reef crystals. My alkalinity is usually at 9-10dkH. Yesterday it was at 7.9 so I dose to raise it to 9 again.
My calcium and magnesium are always high and never go down.
Calcium is at 600ppm and magnesium at 1800ppm. I have never dose those two because they never go down.
I was thinking about switching to the regula instant ocean. What salt mix do you use?
