need salt info/etc

[fishguyxd]

ok tonight out of a new mix 5 gal mix ( from a rubbermade container not display tank)
the results are using "reef crystals salt"
Sal 1.023
ph 8.2
kh 110 meg /L or 11 drops
CaL 280 -300
mag is about 930 (salfret kit) I know it should be higher

So is this ok ?
I usually do not take "all" these tests from a new batch of water.
any imput?
I do hope by keeping all reefers updated someone new in the hobby will get a chance to read and learn.
Someone had a post & link with regards to using epson salt to boost mag
? Is this corect and how safe is it?
Well tomorrow I will test display tank and see what's taking place.
