At some point today while I was at work my quarantine tank was unplugged. Both the air pump and heater were unplugged. Needless to say the water is cloudy and the temperature is 58 degrees!!! I plugged it all back in and shut all lights off in the room. What should I do? Water change to bring temp up? Quarantine is holding a yellow tang being treated for ich. Has been doing great but he is currently brown instead of yellow! PLEASE HELP! Im freaking out!
