Salt Mix Recommendations

[nano_ryan]

So I'm new to making saltwater, been using LFS water and they use Fritz salt.
Finally ordering an RODI system and going to be making my own saltwater and all.
I know it's ideal to use to same salt you've been using with your system, but Fritz salt is like 2-3x's more expensive than some of the other brands out there.

Is there an alternate a bit cheaper I can use for making my own?

I know there's a lot of differing opinions on the "best salt mix", but really I'm just looking to match actual sea water levels.

I use classic instant ocean for all my tanks, works great.
