Does Instant Ocean have a new formula?
I just began using a new bucket of Instant Ocean with the new label. I had heard rumor somewhere that they were changing their formula for increased calcium and magnesium so I tested the newly mixed up saltwater to see.
At a salinity of 1.024 that had been mixing for 5 hours with RO/DI water and a powerhead I measured the Calcium to be 400 with a salifert kit, Alkalinity was 11.5dkh with elos and Magnesium was 1275ppm with elos as well.
In the past I've tested the 'old' Instant Ocean with 'old' test kits and at Salinity 1.025 I received Ca 340 with salifert, Alk 12dkh with elos and Mg 1200 with elos.
It seems like they may have increased their levels but then again there is a lot of room for error with how I mixed and tested. Has anyone else tried this?
