What is considered the best salt?

What salinity do you mix to? Calcium carbonate is already supersaturated at normal salinity, and raising salinity risks precipitating it.
Also - don't know if you caught it - this is ESV. The bulk of the salt is solid and the "rest" is already in solution.
 
The best salt is:

  1. The cheapest
  2. Closest to your current/desired parameters (for stability sake, or if you want to get to a different long term parameters
For me that’s instant ocean because it is the cheapest, and parameters I don’t care too much about since I have a calcium reactor for the big params.
 
The solid components are just NaCl and MgSO4. The liquid stuff is saved for after close to final dilution and use. I don't know what the final salinity is before dilution. It's something like 8.something x final concentration.

Ok, I do not know exactly what is in each part of the ESV mix, so perhaps that can work out if it has some advantage for you.

The only advantage is the time saved in dissolving the solid components when I'm in a pinch. And I don't have the complication of precipitation while storing the solution. The components that could precipitate are stored separately in the liquid ESV components. I'm in a kind of unique situation in that my aquarium is in my office and we RODI on tap in our lab prep space.

Ok, thanks. Makes sense.
 
Well I guess it's time to start thinking about salt for the new R2R HQ Mariner Tank!
 
I’m using TMPro do any other salts mix cleanly that provide significant savings? I use a brute and like to keep saltwater mixed for a few weeks. Reef crystals leaves a film that I don’t like in previous experiences.

I use 55 gallon barrels and Fritz RPM blue. It mixes and is ready for me in about 30 min and I always have some in the barrel with zero issues. My barrels sit in a climate controlled closet off the garage and I don’t use a heater… just a Sicce ultra zero utility pump sitting in the bottom that is constantly churning the water. That pump running 24/7 keeps my saltwater temp around 76-80 degrees.

Of course Fritz used to be $60 bucks but now it’s more like 80 for a 200 gallon box.

ESV. Slightly higher alkalinity but on sale the 200g refill is $101. You will get close to the full 200g as well.
 
what the heck Instant Ocean?!?! Large stick in my salt. I’m switching.
