My Coral Quarantine Tank has been cloudy all of a sudden for two striaght days (it does clear up eventually later in the day). I don't use any sprays or cleaning products in the same room as the aquarium. All the parameters are in check, in addition to the coral I have two clown fish and some snails in the tank. When the tank is cloudy my Zoas close up and everything thing else kinda stays open. Could the Coral be spawning? I'm sure I have aptasia in the tank also since it is my Quarantine. Could that be it? Any help would be appreciated. Thanks
