So I very recently finshed cycling my 20 gallon (fishless cycle) and got some fish. We bought all the fish yesterday and put them in. Its been 24 hours or so now and a obvious white cloudniess is forming in the tank. :eeek: :eek: :eeek: From my reading here, its appears to be a bacterial bloom. The fish seem ok, but of course I am concerned. Will the bloom fade away in a day or so?

Right before putting in the fish, I did two large water changes prior to the fish. Lets see... I did a 50% water change the day before buyign the fish (Thursday). Then did a 75% water change on Friday morning. Friday afternoon I bought and added the fish. It is now Saturday afternoon/evening, and the white cloud is umistakeable.

P.S. Reason for the big water changes was for nitrates. I had did the first one, and then after reading more on the site, realized I probably shoudl have done a 75% as opposed to the 50% that I did. SO I did the other larger one.
 
Newly cycled tanks often have bacterial blooms. As long as the fish seem unaffected I wouldn't give it another thought - it will clear by itself (often overnight) as the bacterial populations in your tank balance themselves out and everything settles. While the tank is settling in, try to feed the fish sparingly (only once a day unless they're very very young fish is just fine) and monitor the water quality just to make sure you don't get an ammonia spike.
 
Thanks Blinky. Kinda embarrasing that I got so concerned about fish. Heh
 
Being concerned about the welfare of your fish is nothing to be embarassed about! If I had just set up my first tank I would have NO idea that cloudy water was common in a new tank, and I would be worried too! I think you're doing a great job looking after your fish :D
 
The folks who worry me are the ones who aren't concerned about the welfare of their fish. Of course you won't find a lot of those people here. This and many other forums like it are designed for people who are concerned and need info. :)
