Up way to early this morning so had time to open up a different bag of RC. Just don't feel right yet doing this just once.




New bag

25C

35ppt

Alk 12.2

Cal. 530

Mg: 1530










Interesting how much higher this is compared to the 2009 results. I've also have seen a few recent (past 8 -12 months) of people reporting really high Mg levels from RC.




From 2009

Reef Crystals

490

13

1440







Acccording to IO RC mixed to 1.026 or 35ppt Calcium should be around 455 and Mg around 1345. Of course that's their marketing. I don't think I've seen anyone report Mg levels under 1400 for RC before.




I just dropped off the samples last night to be sent to Triton.
