It was brown and white, but the brown went away after about an hour and, what was left was white. No ozonizer or UV sterilizer on this tank. Alk is 11.5dKH and calcium is 460ppm.
When I got home and discovered how cloudy the water was (enough that I couldn't see many of the fish or corals in the tank), I changed the configuration and took the media off from the return and just placed it in the sump. The cloudiness is almost completely gone from the water now - about 2 hours later.
