salts ?

[id52]

Would like your input on what type of salt mixture would be best . I have fish with 40lbs live rock only. I am in the process of purchasing a R.O. unit . It is a 5 stage unit (GREAT PRICE)
(1) kent sea salt
(2) Coralife Marine Salt
(3) Oceanic Natural Sea Salt Mix
(4) Red Sea Salt
(5) Instant Ocean Salt

I used Kent and now I use Instant Ocean. No trouble with either.
As long as this is a salt thread I'm gonna ask. Does it hurt to use different brands, like one this month and another next month. My LFS told me not to switch but I didn't understand why.
