so i made an impulse buy and didnt know about the cycle so i bought 8 serpae tetra and 3 paleatus cory. i have a 10 gallon kit came with filter and heater i keep the temperature at 80f four of the serpae have died up until yesterday i found out i have to change the water when the ammonia gets over .25 the tank is a week old as of today. i feel bad having killed so many fish i don't want more to die. every time i change the water i add quick start and i also have the readistart nitrifying bacteria starter that i add everyday i also have the freshwater master test kit and check the water everyday. what can i do to keep the fish alive and ammonia down
