I just picked up a bucket from Bulk Reef, but it was about $65. That sounds like a better deal from PetSolutions, and you don't have to cart a heavy bucket around. The levels seem much more appropriate for my system.
Their advertised levels are:
- Salinity: 1.026 sg
- Calcium: 420-440 ppm
- Alkalinity: 7.8-8.2 dKh
- Magnesium: 1250-1310 ppm
My measured levels after mixing 5 gallons for 24 hours are:
- Salinity: 1.026 sg
- Calcium: 380 ppm
- Alkalinity: 7.8 dKh
- Magnesium: 1280 ppm
Got the same on the way from BRS. Like the numbers you tested.
Did you test also for Potassium?
