My water has been cloudy for a while now, seems like it started after I noticed the new fish from the crappy lfs had ick (they're dead now, at least my original fish are ok). I added a bunch of salt (per label instructions) and I turned up the temp to like 85f. I assumed it was the salt that was making it cloudy but I have been doing nightly water changes of at least 25% and it is still couldy! What could it be? See pics below.

Ok, I just did a test and the warm water comes out of the tap and its all cloudy looking, this is normal i guess since the water is heater, whereas the cold water is crystal clear. So I guess I will fill with cold water instead of warm water and see what happens. What do other people do?

BTW: My danios LOVE to swim under/through the water as I add it to the tank! They are so fun! :D

Is your cold water parameters from the tap, the same as the warm water?

I don't have problems with cloudy waters, but in my 125 gallon tank, I use straight warm tap water for WC and Gravel vacs. Both my 20 gallon long (shrimp and L-046 Zebra) and 10 gallon QT tank, I use dechlored, heated, aged water.

You use any medication for Ich? Could have killed off your bacteria and is undergoing a mini-cycle.

What are your water parameters?

Good questions.:thumbsup: Cloudiness can be caused either by bacterial bloom or overfeeding.

Another question would be what kind of medicine was use.:)

Just a thought


Are those live plants in your tank?
If so check for decaying plant matter we went through months of cloudy water tried everything under the sun to clear it up ended up being dead plant matter under the gravel that kept making it cloudy.We got rid of all the live plants and never had a cloudy problem again.. :)

My current readings are Ph 7, Kh 5, everything else 0. They are real plants and I pick the decaying leaves off when I notice them. I did not use any medicine for the ick, just pumped up the temperature and added salt. I havent checked the difference between the cold/hot water from the tap...so when you people fill a glass bowl with cold water, then hot water, it looks the same? I thought hot water was always cloudy because it is heated (and aerated?)?

Do you really use HOT water from your tap? I use warm water for one of my tanks, which I make sure if roughly 75-78, and even that isn't technically all that warm, feels slightly cool to the touch. Unless you're giving your heaters a nice kick-start, I wouldn't add hot water to your aquarium...it contains dissolved metals, bacteria ect, all the stuff you DON'T want in your aquarium. The cloudiness comes from dissolved air, which is released in the form of fine bubbles when cold water becomes warmer.

Er...Mike was right.:mrgreen: "Hot" and "warm" are different terms. It's probably warm and we do prefer it rather than hot which could have killed the fish or worse, cracking the tank due to temperature variations.:blink:

Here's an idea: instead of using warm or hot 'tap' water when preparing your new water for the tank, use only cold water, then add boiling water to the cold water in the bucket, until you get the right temperature. I think that is better than adding water that has been heated by a hot water tank. :) Another thing I did which made my water crystal clear, is using extra sponge material in your filter media.

I have been using warm water ~80f or so, certainly not hot! I did a ~40% water change last night and used colder water than usual (so that the water came out clear instead of full of bubbles, etc) and the water look sbetter today. I will change more again tomorrow. Thanks for the input!

so.... my water is cloudy again! I gravel vac's last night in hopes of clearing it up and now it is even worse today.....really don't know what is goin on here.....my only guess is my filter's aren't doing their job? I have:

1 Eheim 2213 rated for ~60 gallons
1 Fluval 204 rated for ~40 gallons

So I have ~100 gallons of filtration for a 90 gallon tank. I am thinking I should get a third filter now!

my guess is a bacterial bloom...that usually makes the water cloudy..

Close, I think it's an algae bloom since it is greenish and when I change the water, I can see in the sink that it is a pale green color. Looks like I will be getting an UV Sterilizer? Any recommendations (price/performance)?

Not too familiar with UV Steralizers, haven't used one, but maybe it could have something to do with your lights? How long do you keep them on? Maybe significantly lessen the amount you have them on for, or keep them off for a while.

I am positive that it may have something to do with the following factors:
1. Overfeeding
2. Bacterial bloom
3. Carbon leaching out muck after being stuck in the filter longer than when it was supposed to be removed.
4. New gravel

UV Sterilizers and lighting have nothing to do with the cloudiness.

As for algal bloom, how many wattages does your light have? What about nitrates and phosphates? High level of phosphates and nitrates along with too much lighting can caused algal bloom. Exposure to sunlight is also another factor.

Yeah but he stated it was a greenish cloudiness, which points to an Algea Bloom. Reducing light, and reducing feedings will rid the tank of the green water. Be sure to increase oxygen levels by aerating the tank, as the algae will consume the oxygen and it can get to extrememly low, deadly levels at the night time.

You could also try covering the tank completely so no light what so ever penetrates the tank.

I did skip accidentally to your post without looking at Josh's new post.:mrgreen: The UV sterilizer is supposed to be of help eliminating the floating green algae. Other than that, try what Mike has suggested.:)

but he may not need to go to the trouble of FINDING a small UV sterilizer for his tank if he just eliminates light to his tank for about 3 or 4 days, and minimizes the feedings as well...this is supposed to work, but i'm not sure about a planted tank...your plants might suffer w/o the light.
