Cloudy film on fushtank water

Question
Hi, I have a 40L(10.5 gal)  tank and a 130L( 34.4 gal)  tank I have been waiting for my big tank to cycle and about 2 weeks ago it was ready for fish. The ammonia was at .25 but after 4 hours of my fish being in the tank, the fish were gasping at the top which I read meant there was too much ammonia in the water. I transferred those fish back into a smaller tank which has been running fine. After 2 weeks of waiting for the ammonia to decreases it had actually increased to 4.0 and a white/ cloudy, slimy film had formed on top. We emptied the tank, cleaned the rocks, did the filter, set it back up and now it has been 1 week and the ammonia is at .5 and the film is forming again. I don't know why this is happening!!!! I use stress coat which takes the chlorine out of the water and I have a CF 1500U filter which has a switch which is apparently meant to stop algae build up but i dont think its working but it has a water skimmer. Please help!?!?!?

Answer
Kiarah,
The cycle process can take 6 weeks, sometimes longer. When you added your fish, the cycle was not finished. Keep the fish in the other tanks until your ammonia and nitrites have registered zero for 7 days in a row. This is a long process, but it is better for the fish in the long run. The first 2 weeks of the cycle process is when the first bacteria bloom starts. This is the bad stuff that can kill the fish. Approximately, 2 weeks later, that bloom starts to die off and the second one sets in. This is the bacteria the filter and fish need to stay healthy. It is between these two that the ammonia and nitrites start to raise. When this happens, you will begin doing daily water testing. Once you have tested, you will start doing the water changes. The amount you change will depend on the levels of ammonia and nitrites. Again, the testing and water changes will be done daily. Once you have tested the water and both the ammonia and nitrites levels are both zero for 5-7 days in a row, the filter has been cycled and you are ready to add fish. If at any time during the 5-7 days of testing, either level goes up, you will start the whole 5-7 day count down all over again.
