Extremely High Alk In Instant Ocean Salt

[Aquaticguy11]

Just bought a bucket of instant ocean salt and made a fresh batch if 1.025ppt saltwater and the alk tested 16dkh!!

Has anyone seen or heard of this?

Thanks

Is it worth a 2nd test just to make sure?

Done it with 3 different test kits...

Could it be anything in part with the spring thaw?

What do you mean by that?

I've never kept track of a measured kh during the different seasons but I do know my own tap water has different characteristics during the spring thaw. Although I'd think this would more apply to freshwater tanks than salt as freshwater aquariums typically don't use RO water.

Was just spitballing.

Its fine just do smaller waterchanges. It has been discussed here a few times.
