I tested a batch of HW Marinemix reefer that was about 3-4 weeks old. It tested:
Potassium- 350
Alk- 7.5
Calcium- 420
Mag- 1410
Then I tested a newly mixed batch and the results were:
Potassium- 330
Alk- 7.8
Calcium- 400
Mag- 1290
I am surprised at the low Alk and Potassium. The Alk is supposed to be around 9 from the BRS tests I have seen run and the Potassium seems awful low as well.
I was considering moving to Brightwell Neomarine instead. I keep my Alk around 8.5 and is seems Neomarine is closer to that.
Anyone else with similar results?
