I have had my tank up and running for over a 1 1/2 years, all of a sudden my tank has extremely high ammonia, of 4.0, lost 2 fish already, addednew carbon, did 20% water change, ammonia still high is there anything else I can do?

Hi:
may i ask what have you done to the tank recently? removed fish, added something to the tank, big water change, power go out? etc.
There has to be a reason why you are recycling. Also have your water tested by another place to ensure you test kit is correct.
W/ that saidconsider taking the fish out of the tank, and bringing them to a friends or the lFS or set them up in your qtank 9should you have them) these fish won't handle high levels of ammonia for very long.

I have a 50gal tank with a fluval 304, all I did was do a water change last sunday, but I may have cleaned the filter to good, how long does it take for ammonia to start dropping

If you did and killed the bacteria, you'll have to cycle your tank again. The best thing to do is remove the fish and place them into another cycled tank. If you don't have a cycled tank, immediately stop feeding and do regular water changes (possibly even twice a day) to keep the numbers in check until the bacteria come back. There cannot be any bacteria killing cleaning agent left in the filter, or its going to take much longer. . .
Best thing you can do is stop feeding your fish for a few days to keep the ammonia/nitrite production down.

What do you mean there cannot be any bacteria killing cleaning agent left in the filter, should I clean the filter again, I have the foam on one size, and the bio balls in the 2 compartments and then carbon

If you used soap which kills bacteria or anything, chances are there is residue from that unless you rinsed it out REALLY REALLY good. If there is any soap/cleaner residue there, that will kill your bacteria as well - which is a bad thing. . .

All I did was pour some tank water on the bioballs, no I did not use soap all I used was tank water, what do you suggest I do, as know I have 4 fish alive, should I do another water change it is a 50g tank

I brought your question to my local fish store (lfs) and they said if you cleaned your bio balls with your tank water, you should be ok with not disturbing your biological filtration, more importantly your ammonia:
here is what they suggest: go your local fish store and get "ammonia detoxification". your ammonia levels will still read high, but the actual "toxicity" won't harm your fish becuase you have de-toxified your ammonia until it has completely broken down.
Good Luck!
