Reef Salt Brand

[whatcaneyedo]

I use two brands at the same time but your poll wont allow me to pick two. Instant Ocean with a Magnesium Chloride and Magnesium Sulfate mix because it is inexpensive and has high alkalinity but low magnesium. Then in another mixing container I use Seachem Reef Salt because it isnt that much more expensive and has balanced magnesium and high calcium. I go though 40gal of newly mixed up saltwater every week so cost is a big consideration for me. In the past I've also tried Tropic Marine (too expensive), Kent (unreliable and now unavailable where I live) and RedSea (also now unavailable).
