Ok guys i need some serious help. When i first started out my ten gallon tank(it has an underground filter system) I put this stuff called stress zyme in along with 1 platty. 1 week later i had stuck in another dosage of stress zyme. That night i went to the LFS and the guy said that stress zyme didnt work and to stick 1/3 bottle of a cycle in when i got home. I did. He said my tank should be good in 2 days. Wrong, it wasnt. Because of the high ammonia ( 4ppm ) I took my platty out and stuck it in a smaller 5 gallon tank and am doing 1.5 gallon water changes every day. Now last night i went up to a different LFS and was told to buy BIO-Spira and to add 1/2 of that when i got home and my tank would be fine the next day (today). My amonia level is at 4ppm and nothing has done a thing. Should i off changed water between the different chemicals or somthing? I am clueless as what to do now. Can somone please help!
