If it is a new set-up and you are doing a fishless cycle, cloudy water is normal and can last a few days. There should be no need for water changes or filter changes because there are no fish.
If you are cycling a tank here is a link to help, if not, then I guess I need more info to help.

Sorry I can't do betterWhy is my water still cloudy?It takes approximately 3 weeks for a tank to cycle through completely. Is it fresh water (the tank I mean?) because you can add conditioner to the water (you can get it at the pet store) and that will help.
My husband and I went through the same issue just a month ago. :) It WILL clear up...Just takes time. :)Why is my water still cloudy?there is no need to keep changing the water and the filter if you are doing a fishless cycle, you now have to start over because the bacterias build up in the filter. just give it a few days to settle down. it will clear up. it is possible that it is your tap water. give it a week and if it does not clear up, as this is normal during this cycle, then remove the water and put softened bottled water (in the gallon jugs). don't keep adding chemicals either. there is a limit before the water isn't safe. the hobby of fish is not race there for you should be in no hurry. it takes time to make everything perfect. it took the world Millions of years to give the oceans what they have. good luck.Why is my water still cloudy?give it some chance.. try at least a one month to filter the waterWhy is my water still cloudy?get a bag of fresh prawns ( a handful will do) wash it, then put it in a tied up nylon stocking and place it in the tank. Leave it in the tank for a month, this will cycle the tank. When your nitrates start to rise, then do a 50% water change and then it's time to add your fish.
