Why Does My Fish Tank Get Cloudy After Water Changes?
by Aquaboy on Wednesday, June 22nd, 2011 | 4 Comments
My fish tank is under populated, cleaned regularly, all chemical levels are testing safe (ammonia, chlorine/ chloramine, nitrate/ nitrite, pH, etc) and yet about a day after each water change my tank stays cloudy for about a day or two. This means a cloudy tank every week and can’t be good for my babies! I use aquarium salts, Top Fin water conditioner, and Amquell plus during my water changes (we have high chloramine levels in our water here and that doesn’t evaporate out with aging the water first.)

you are adding too many chemicals, and probably too much salt. Unless it is a brackish or salt water tank, Stick to the dechlorinator or stress coat with dechlorinator, and avoid all other chemicals.
Answer is;
Not changing charcoal on a regular basis, this removes cloudiness and gasses. your filter is not set up yet
Use carbon in the filter and change regularly. With the high chloramine levels, there might be some the water condition misses (Prime has instructions on how much chlorine/chloramine it removes and how much you can safely increase the dose to treat higher levels). The chlorine/chloramine is killing some of the beneficial bacteria and causing a mini-cycle. Using activated carbon in the filter will help remove a lot of the excess chlorine and such that might not get removed. Replace regularly.
Also, you might be adding too much salt. It is not some magic tonic and really is overused when it is not needed.
I had this same problem when my municipality switched from chlorine to chloramine and my water conditioner only treated chlorine several years ago. I did not use carbon at the time. This was in a 7 year old tank and suddenly started happening, and I soon found out why when I found out about the switch.
Also, less volume of water changes at one time can help too.
Aging might still help even with water conditioners to get out saturated air and the like. Also cut out the salts.
And do not clean the filter the same time you do a gravel vac or water change.
Are you testing your chlorine or just assuming it is 0 because the conditioners?
Maybe you put to cold or hot water or salt or chemicals hope this helps
