    I have a 20 gallon freshwater fish tank. I put 1 dalmatian molly and a black molly in yesterday. The water is a lttle cloudy. When should i do my first water change? How much %? (All the levels are normal according to api master, before i put fish in)

    You should do a 25 % change at least once a week, but keep an eye on your water perameters. There are no bacteria to get rid of nitrates and to should be kept below 20.

    For a 20 gallon tank, I recommend two 5 gallon water changes per week.
    Be sure to match temperature as closely as possible and don't forget to use dechlorinator.
    Good Luck & Welcome To Fishlore :)

    I misinterpreted you're post and am sorry, lol. ANYWAY.

    I'd do a 15% water change every week or so. but use the test kit to guide you. I stand by my initial post that you really only need to do water changes when the ammonia and nitrite are showing too high. It's always better to test and have a w/c schedule though. Little bits more times are better than lots of water at once. Especially in smaller tanks.

    Cloudiness in the water is an oddity if the tank is established.
    How old is the tank?
    Is there any other reason that the tank would be cloudy?
    Is the cloudiness green at all?
