Salt Mix

[Europhyllia]

I started out with Reef Crystals but switched after reading up more on salt. I have used premium salt (Tropic Marin) in the past and it was okay. Part of my decision was based on studies in regards to heavy metals/pollutants in the salt.
Right now I am doing a lot of water changes on a big tank though and I switched to the cheap stuff: Coralife. It mixes up well and even in the big bucket it comes in separate bags so it's mixed evenly and doesn't get clumpy over time.
I briefly switched to a mid range salt - Red Sea Coral Pro- because I was out of Coralife. Didn't like that one. Seemed to mix much less clean and leave white crust/film in my 44 gallon mixing trash can.
I've seen some great reviews on the ESV 4-part salt. Once I am out of Coralife I'd like to try it out.
I think if I go back to premium salt I will go to something that is really different like the ESV rather than similar bucket salt with a higher price tag. I like that you can customize the values on the ESV, that it mixes up completely clear and can be used the same day and I do believe that trace elements may really be better off in liquid form separate than all mixed in and potentially wasted in a dry salt mix.
So for now it's either Coralife cheap stuff or ESV for me.

Here's my ratings (5 star being perfect):

Reef Crystals - ***
Tropic Marin - *** (liked it better than RC but price is so high so I give it only 3 stars)
Oceanic - ** (dissolved okay but left a lot of deposits)
Red Sea Coral Pro - ** (again too much deposits)
Coralife - ****
ESV - B-ionic - will try next
