H20 ocean salt is just rebadged Red Sea salt

[TonyR]

Hi

I have been getting on well with the H2O, my aquarium is still growing well.

With regards to the KZ kit beware as i have had a faulty kit in the past showing my aquarium and salt mix at 260.
I ended up overdosing Potassium chloride and killing a few corals. A fauna marin kit and a new KZ kit showed my Potassium was actually off the scale. Test a few aquariums and you will probably find they all read around 260 if the kit is faulty,
