Instant ocean salt

[up_syndrome]

Just picked up a new bag
It’s mixing at
1.025
8.2 alk
490 cal
1200 mag
Would these numbers be considered acceptable for a soft/lps tank

Absolutely! May need to boost the Mag, but that's easy

I'd say it's fine. These tanks were started and maintained with instant ocean.

Just two of several. It's all I've used for 9 years.

EDIT: I have to admit I don't test my fresh saltwater mix and I never test mag in my tanks. I target 8-9 dkH for alk so it's perfect for that range.

Can I dose the magnesium right into the pre made water after I mix it ?

Salt is fine, numbers seem off….most likely testing error if it’s regular IO

I would assume the salt has more mag than your test indicates. Mag testing is notoriously error prone.

If you raise the specific gravity to 35 ppt, everything will rise a bit, but you are fine where you are.

The calcium may also not be that high, but it is fine.

I use normal IO.
