Just set up a 65gal saltwater tank. Have 2 external fiters, undergravel filter, and a quicksand filter. Set the tank up 5 days ago, everything looks good except the water has a hazy appearance, kind of like your vision through dirty contacts. Gravel, rocks etc were all throughly washed before adding to tank, filters working fine. Just added 4 Damsels today, no fish until those guys. Is this something that will clear up, or do i have a problem?
