I have been battling phosphate for about the past month or so. I have read many other threads regarding this issue and I have come to the conclusion that I am somehow introducing phosphate to my system. I had a fellow reefer come by and test my phosphate level in the tank and it is about 32ppm which aint great. Next we tested the water coming out of my s month old r-o unit and it was 7ppm. This now makes me suspicous of the salt I am using which is instant ocean and not the RC. Is it possible that my salt brand could be loaded with phosphate? Is there a brand of salt that has a reputation of being phosphate free? Could I benefit from A salt upgrade? Any help would be appreciated.
