What can I do about cloudy fish tank water?

We set up a 15 gallon aquarium about 2 weeks ago . There are 5 fishes in there. 2 mollies, 2 angelfish and one platys. The water has started looking cloudy. My husband just vacumed it and cleaned the filter and it's starting to look a little better, but what can I do in the future to prevent this? My husband says we need to get some little catfish in there. Anything else? Thanks in advance!

  • Get bottomfeeders and snails to complete the ecosystem in that tank. Those eat leftover food and crap that builds up in your tank. You can also ask about water additives at your local pet store. However, I don't recommend frequent water changes because the stress from doing so can kill fish (talking from experience).

  • is it by a window? If so decrease the sunlight it gets. Def get a couple bottom feeders but smaller dotn want the fish feeling crowded.

  • Watch those algae eaters though. They will grow to meet their surroundings. I bought one this past summer at 2" long and at the end of summer he was 6" long and disgusting!!!

  • If it's only been set up for two weeks it should not have been cleaned already. You need to get some good bacteria built up in there.
    Did you do a pH test? Cloudy usually means an acid imbalance.

  • add good bacteria and free floating charcoal filters should help real plants

  • The cloudy water is because it is a new tank and has not built up enough good bacteria to take care of uneaten food and fish output. Make sure you are not over feeding the fish. Get declor from the pet store and do small, partial water changes for a few days. Make sure the water you add has been declorinated and is the same temperature. Once the water has cleared you just need to do a partial water change every other week. It just takes time to create an environment that is balanced with enough good bacteria.

  • Take a sample of your tank water to the pet store and ask them to test it for you.
    They should be able to tell you if the ph is off and what to do about it

    Always splash water into a container 24 hours before refilling a tank and leave the container open.
    Empty out about 1 1/2 gallons of water each week and replace. If you can syphon water from the bottom so much the better.

    How long was the tank set up before you put fish into the tank?
