Cloudy Tank/fish Spending Alot Of Time At Top

[atomania]

Hi guys i have an 180 litre tank i've done cycling with fish in as this is what i was told was best, wish i had joined here earlier, anyways ive had fish in it 3 weeks and over the last couple of days the tank has gone cloudy and the fish are spending most of their time at the top of the tank, is there anything i can do to help them, and what is happening?

Thankyou for all your help

Do an immediate water change of at least 50%, preferably more like 75%. It sounds a bit like a bacterial bloom or ammonia problem (fish at the top) but do the water change first to help out your fish.

Do you have a liquid testing kit? If not you should get one right away and test for ammonia, nitrite and nitrate levels. The first two need to be at 0 otherwise the water is toxic to your fish. You might want to read up on what to do with your new tank, and you can do that by clicking on the link below my sig.

You've come to the right place. Welcome to the forum, and good luck.

Do you have a test kit to test the water. I think a large water change will help as i dont think after 3 weeks your tank will be fully cycled and there is possibly high amounts amonia in the tank.

The cloud is bacterial bloom so I'm guessing the nitrite is starting to spike and the fish are struggling to breath


Do a 60% water change and another tomorrow

Remembering to de chlorinate the water and temp match

hi cheers for all your help guys, how long do i have to leave the water in the dechlorinating solution before i add it to the tank?

De-chlorinator is pretty much instantaneous.

Once the dechlorinating solution is added, it can be used straight away. However it is a good idea to try and match the water temp of your new water with the water it will replace. Just boil some water and add it to your new water to get the temp approx matched before adding to the tank.

If the water temp is wildly different then it can stress the fish and also kill the friendly bacteria in your filter.

You can generally just temperature match from the tank unless your water pipes are really ancient. Just let it run for a couple minutes first, and get it close to the tank water, dechlorinate, then add to your tank.
