Hi guys 'm new to the site here, but i need some help big time i have just gotten a 20 gal tank, i always had a ten as a kid growing up, but i havent had one for a while, anyhow, i didnt have any clue about all this amonia and nitrate stuff and it is overwhelming i feel like you have to be a biology major to get this right, so all i knoew was that the girl in the pet store told me to put the tap water chemical and a little of the live bacteria stuff in the tank and let it run for a couple of days ,,, so i did and i thought this was ok, but i had no idea you had to check for amonia and nitrate, i didnt even know what this stuff was until reading these posts so i got the testing kits and my levels are way high, the lousy part is i have bought some fish, before i knew this stuff i thought i was doing the right thing, so now i have no clue how to get these levels down, i totally didnt know about this whole "fishless cycle" thing but is this something i can do now even though i've got the fish in the tank, also i have planted several plants in my tank but it's been about a week and they are starting to die, i'm so fustrated because i feel like a moron i thought i set everything up right, any how what can i do to get this thing on track??? i also bought some amonia neutrulizer just to fix the water so my fish survive for now, but can i start the bio filter now even though the fish are there and if so have i already started it because ive put the bacteria stuff in a couple times now anfd how much shoul i put in and how often and how long till my tank is healthy??? someone pls help i'mbummin big time here, the funny thing is the couple of fish i got in my tank seem pretty well so far, the tank has been running for a week n a half or so
