Cloudy Freshwater Tank???

Hello everyone, I seem to have a reoccurring problem with changing the filter with my tank. My water will be crystal clear for months. I assume that I need to change the carbon insert in the filter since the instructions direct you to replace the carbon every month. But once I replace the carbon with a new one, my water gets all cloudy and muggy. It seems like a algae bloom maybe...??? I made sure to rinse the carbon before putting it in the filter.

Any suggestions besides using the water clarifier or that's the way to go?

Yes leave your old filter media in the filter with the new one for a day, so it helps put the bac into the new media. It is normal to do that to the water when you change the media. it is a mine cycle. I do have a question do you clean the substrait at the same time you chand your media? If so that has a big part to do with it as your taken a lot of bac out of the tank. What is your schedul when you clean your tank.>>>(first week) I do 25 percent water change ( second week) 25 percent water change and sub vac the substrait ( third week) 25 percent water change ( forth week) 25 percent water change with the filter media.

when i change my media out i have the same issue but it usually clears up after a few hrs or so. mollies is correct in what he said, but i would like to add. the cloudieness could also be from debris that is caught in the filter being shaen loose when you take the media out and then it is then put into the water which would cause cloudy water. but then again we may be talking about two diffrent types of "cloudy" water. what i do to prevent this is just turn my filter off when i do the replacement and when the new media is in place turn the filter back on.

Good advice from prevous responders. But on your last question, don't use chemicals to "clear" the water. These stress out some fish terribly. Always find the source of the problem and deal with it, as in this case nothing to worry about and some suggestions to prevent it next time. Stay away from chemicals. The fish have to stay in the water no matter what you put in it; they can't escape. And these things do stress them. Same applies to any "stuff," proper tank maintenance is the best preventative and cure.

What kind of filter is it? I see in your aquariums tab you have 2 tanks. Which tank is it? Do you have a test kit that you can test for ammonia and nitrite when this happens? If it's a filter with just a carbon cartridge than you are throwing out the majority of your beneficial bacteria when you change it out. Instead cut a slit in it and dump out the carbon. Put in a new cartridge but leave the old "floss" in as well so it can seed the new cartridge. I actually don't run carbon unless I need to remove meds.

thats what I was thinking....I thought carbon was used to remove medication after you treat for disease. What kind of filter are you running? There's no need to "change" out the filter media that much at all...you can use the filter floss which jeaninel was referring to. You can simply swish that stuff around in some water from your pwc....

I agree with money...when i do my pwc, the water is usualy cloudy for....maybe an hour or so, after that it clears right up and return to normal.....

wow i never thought of leaving the old one in with the new one. this time i didnt vac the gravel when i changed the carbon. but like a week later when i realized how cloudy the water was, i checked all the levels and the nitrates were getting high, not dangerously, but thats when i decided to do a 30% water change. its been 2 days and no improvement on the clarity of the water.

i usually do a water change with a vac of the gravel every week and a half to 2 weeks. i had perfect balances in my water quality with my old media with that schedule and didnt even think i needed to change the carbon but it was like 2 months that i had it in there and figured i might as well replace it before i was too late.

right now i have a aquaclear 110 running on my 75 gallon tank. i want to stay away from using chemicals. ive tried using the water clarifier and it didnt even work that well. should i do another water change? ive already thrown the old carbon insert away. am i going to lose my fish???

sounds like you sent the tank into a cycle. during the cycle it is common for the water to become cloudy i know mine did for a while when it cycled. cant tell you exactly why it happens all i know is that its common for this to happen hopefully someone can iterate more on this for ya.

Well, in an Aquaclear 110 filter there should be no problem changing the carbon insert because there should be a sponge on the bottom for mechanical cleaning, then the carbon insert (if you want to use it), then Biomax on top for your biological filter. Is that what you have in your Aquaclear? The Biomax (ceramic bead shaped things in a mesh bag) you shouldn't have to touch. That is where your bacteria will colonize. The sponge can be rinsed out in used tank water and the carbon insert would be optional if you want to use it.

yeah jeaninel thats the set up i have right now. so far its been almost a week since my last water change and i've also used the water clarifier twice and conditions are the same. i'm not sure how long its supposed to take for this water to clear up but it's not getting any better. all my fish seem to be doing fine though...active and full of life. i'm going to try to do another gravel vac with a water change either today or tomorrow. hopefully this will help
