No worries, John
You are correct, my friend...
"I will say that I am not at all partial to crystal sea mix from a [long] history with it. I would pass or wait for Tropic Marin or IO anyday."
The sea salt issue and all of its baggage has never been an issue for me. I'm a good and conscientious aquarist... I QT all of my livestock for a full isolation period, I feed them well, conduct frequent (weekly or better) partial water changes, have excellent and well-attended other nutrient export mechanisms, etc. I simply don't have "mystery" problems through the years that I care to ascribe to sea salt brands, armpit hair... or the staggering amount of garlic on my breath.
As a consumer I look for QC, reliability and time-tested history. We get that from IO and a couple other of the currently roasted brands. I have made a handsome living using it too (tens of thousands of gallons of IO through my coral farming greenhouse in a decade) and enjoyed it as an aquarist. And I have never recieved a single free grain of salt/sample from them (no other implications here on other folk either... just my state). It is what is is... a good and reliable sea salt (IO).
Now that Tom Frakes has refined his personal formula and is with Omega... I will be trying it and may very well exchange my use of IO freely with it or replace it altogther.
If I ever give up hope on being handsome and become rich instead, I will use Tropic Marin faithfully
Better yet, I will get my hands on that crazy expensive sea salt that Tetra makes for the Japanese market.
As far as Crytal Sea... isn't there anybody that remembers when this stuff was "Forty Fathoms"?!?!?!? The very name struck fear in the hearts of aquarists. Wow... Some of the old salty dogs need to speak up and remind the new folks about the weak history of this entire product/brand line. How about those events of water changes where all of the snails/mollusks and echinos/starfish are stunned for days or even dead afterwards? Anybody?
Better yet... how about remembering the adage that "Good things are seldom cheap, and cheap things are seldom good."
Again... just one man's opinion
Kind regards John/to all...
