Rea sea coral pro always mixes with DKh reading really high. I used to use ESV but the price was just too much after they discontinued 200gal box package.
I started using HW marine mix and I liked it, mixed around 8-9dhk , 430 cal , 1300 mag still kinda pricey though.
My LFS store has been selling 50 gallon bags of coralife salt for 8.99 though so I switched again to save some coin, it mixes at 9dkh 450cal and 1400 mag. Happy with it and the price.
I figured out the price increase was for the nice plastic 5 gal bucket they ship their stuff in. It's nice to have 5 gal buckets around so I couldn't care less for the price increase. I shop around for the best price with Marine Depot usually being cheapest. I've been using ESV for over 2 yrs now and won't switch for fear of upsetting my system.
