8 comments on “How Do You Clear Cloudy Aquarium Water?

  1. Ok I’ve done all the cutting back on feeding,water changes,and it seems my tank water just won’t go back to when it had that nice clear water,I no its not good to take out more than 30 or 40 percent of the water change every other day but I’ve been doing it every day and it still won’t go back,can some one help out please?…

    • What color is the water? I it has a green tint, the problem is algae and an indicator of too many nutrients in the water. Do you have plants in the tank? Have you tested the nitrate levels?

      You also might want to test the water you are using for water changes. It could be that it is high in nitrates, in which case doing water changes with it would not help the problem. In that case, you would want to use some form of purified water to make your water changes.

      If your cloudy water is white, it is an indication of a bacteria problem. There are products that can help with that.

  2. hey my water in my tureume is cloudy i did a water chang and that didnt work i also add water cleaner into it to remove the ph that didnt work so can it be the rocks or the drift wood that in there

    • The problem could still be excess nutrients in the water. Have you tested for nitrates? If they are high, I would suggest more water changes and gravel vacuuming. It is possible that the other things you mentioned could be causing problems, but high nutrients are the most likely cause.

    No matter what I do, my take won’t clear up. The lady at PetSmart told me to feed my Guppies 3 to 5 times a day and each time I do, the fish act like they’re starving. Any other suggestions?

    • Three to five times a day is way too much. Once a day is plenty. Fish will always act like they are starving.

      Have you tested your water lately. With that much feeding, there is a good chance that your parameters are way out of range. I would be very surprised if you don’t start losing fish or have an algae problem soon of you don’t have one already.

    I have cloudy water that foams at the top. I was told that it is caused by changing water to offen (once a month about 1/3 to 40% . The fish store expert told me to add bacteria and wait. It’s been three days with no change to date.
    Please advise.

    • Your water change schedule sounds about right. How old is your tank? How many fish do you have in your tank, what kind and how big are they? How big is your tank? How often and how much do you feed?
