I have been using Oceanic Salt for the past year and haven't had any problems with it, however that doesn't mean that it is the best salt out there...
What salt mixes out there do you use? and how well has it worked out for you?
What do you think is the most cost effective salt brand out there? consider cost, amount (200 gallons ect) ease of use, dissolves easily, concentration of calcium...
I have tested a fresh batch of Oceanic salt mix last night and the water specs were:
RO Water used : 6 tds
Ammonia : 0
Phosphates : 0 (from what I can tell, the colors are hard for me to distinguish)
Nitrates : 0
Calcium : 330 (kinda low)
