I have Instant ocean reef crystals,
used Salifer for all 3 tests.
430 ppm- Calc
10.9 dkh- Alk
1095 ppm- Mag
I feel that Mag is too low and this would be a problem since I'm wanting to keep Mag around 1350-1450 and there would be a spike every water change, I'm thinking of trying red sea pro salt, I've heard they have some nice levels.
