Cycling tank

I got a 220 for my other fish as they were growing too large for the 150 i need my new tank to cycle i got an overhead filter and an eheim classic canister all was well until the eheim canister's carbon decided to spit out everything it had absorbed now from ammonia 1
0.2 to 10+ should restart the tank or wait a little longer

Fishless used to have fish in there just to get 2 ppm of ammonia then i removed the fish to prevent anymore ammonia in the tank i forgot about the carbon and it released ammonia in the tank i used stress zyme in the initial cycling process but now the ammonia is is more than 8 ppm on the freshwater master test kit
