As of today I am still not able to find quality Sulfur media online. There are a lot of sellers selling 99.0% pure prills, but almost no one has 99.9% pure prills. I am not sure what's the difference, but that 0.9% impurities can be anything. Yesterday ordered some 99.95% pure media, I hope the ebay seller ships it soon.

Meanwhile, my Nitrates are around 25ppm. Softies and LPS seem to love it, but my SPS are definitely not happy. Limited polyp extensions, muted colors, no white growth tips. My Blue Oregon Tort was super deep blue color, now its starting to lose its brilliance. Can't wait to get my nitrates down. Trying to swing back the pendulum.
