Best Sea Salt for Reef Tanks?
I'm curious to see which brand of Sea Salt is best for reef tanks. I've used a couple brands so far, one caused brown diatoms to break out, so I ended up switching back to the salt I was using previously. However I've recently found out that the brand I use has low concentrations of the essential trace elements (Calc, Mag, etc).
Which brand of Sea Salt contains the actual trace elements that they claim to replenish?
