Phosphates will cause them to brown out. Do you have a high bioload and feed alot? Is your filtration sufficient? I see a couple of things in your parameters that I would change. You might slowly drop your SG to 1.025, or maybe 1.026. I would also raise your Alkalinity level to the 9-10dKH range, and try to get pH up to 8.1-8.3. How long has the tank been up?
