Why has my coldwater fish tank gone cloudy after adding my fish?
I set up my tank with everything it needed for the cold water fish i wanted to buy. The water was crystal clear. A couple of days later I bought some fish (Blackmoor,Fantail,Goldfish,CanaryGoldfish.) and I added them to the clear water. Then a day later the water has gone very cloudy. I have tried taking out some water and adding more, but it is still very cloudy? Please Help.
When I bought my tank it came with an insturction booklet to set up a tropical fish tank. I have cold water. It also came with 2 bottles of stuff to add to the water. One to make tap water safe for fish and the other reduces frequent water change. Is this the cause of the problem or not. Or is it because of the chemicals from the fishs tanks which i bought.(they came from 4 different tanks). Thankyou
the cloudy ness is a bacterial bloom. it’s caused by the huge amount of waste goldfish put out, and in a newly set up tank only a few days old, there is no established bacteria available to consume this, so it causes a bloom and potentially a lethal ammonia spike.
as it sounds as though you didn’t put your tank through the nitrogen cycle, you will need to do almost daily partial water changes (with dechlorinated water) and invest in a water test kit, liquid kits work best. see the link below for more details on this cycle.
for all those goldfish you need a minimum of a 40 US gallon tank (for 4 young goldfish). how large is your tank and how powerful is your filter?
no, its normal for a tank to go cloudy as bacteria and other chemicals in the water start to work, it will subside in a few weeks. for future reference, you should NEVER put fish you plan to keep in a tank that is less than 2 weeks old
If the tank is brand new, then you added too many fish too early. As posted above, its a bacterial bloom. In every fish tank there is bacteria that breaks down the fishes waste to make it not so lethal for the fish. When that bacteria isn’t there to break it down, your water will receive too much ammonia which will kill your fish. When starting a new tank, its best to add just one, maybe two depending on the situation and how long the tank has already cycled, at a time until the bacteria can naturally grow to deal with any waste that is generated.
its called fish urine… *shutters*
Ah the lovely bacteria bloom. Perfectly harmless and will clear by itself after a good few days,.But its just when your friends come around and they dont believe you and think its dirty.
most everyone is correct, however in order for the tank to cycle you need fish to start , bacteria need food just like every living thing, fish waste will start the cycle, once the levels of waste rise the beneficial bacteria will start to colonize once the coloine is large enough with all types of beneficial bacteria the water with both clear and become none toxic for aquatic life, be Patience, and remember regular maintenance will keep Ur tank and fish looking good . ps regular water changes is a must for healthy fish, nothing likes swiming in own waste, and filters only do so much
