Carbon filtration will clear up the cloudiness quicker...

While it is cycling you need a fish in there to help....the cloudiness will not hurt the fish...do small frequent water changes....then as it settles add the other fish

It will just be a case of giving your filter medium and water time to mature and balance...i really doubt it will be any of your ornaments as it was clear prior to you putting your fish back in


Personally, when i pull my tank down (4ft) completely....my fish go back in as soon as it is filled and declorinator is put in....it is cloudy for 24 hours...then is crystal clear after that....mind you i do run 2 filters....1 carbon and one powerhead...i never cycle my tanks empty
