Your tank was cycled?
Did you possibly forget to add dechlorinator to your water before adding it to your tank? It could be that you lost your bacteria in your filter!
Do you have a liquid test kit? What are the readings of Ammonia, Nitrite and Nitrate?
When you wash your hands before working on your tank insure that your hands are extremely well rinsed, any residue of soap could harm your fish and bacteria. It may be a good idea to use a fresh little face cloth to dry your hands, that way you don't rub residues (soaps, oils) from the towel back onto your hands.
Have you done a water change yet? If not do one now. Keep those readings of ammonia and nitrIte as low as you can. It seems you still have some bacteria left, since there is nitrAte present, unless it is still a left over from before. The fogginess in your tank could be a bacteria bloom, or an algae bloom. Is there a greenish colour to the fogginess or rather white or milkish?
What I meant to say about the towel is, if you dry your hand with a towel that has been used many times before it may have soap and oil residues on it. If you use that towel after you've just thoroughly washed and rinsed your hands, they may end up just as dirty as before! I use a fresh face cloth to dry my hands with to avoid this!
You're doing great doing daily water changes. How much water do you change each time? As to how long it will take for the water to clear up, I don't know, this will depend on your tank. Have you checked your ph lately? Do you know what it was before?
You want to check how the ph is in your tank right now. I don't think your ph crashed but just to be sure.Well I bought the tank new and my tap water is 7.5 if thats of any help
