Hi, I have a 10g tank and I'm having an ammonia problem. I'm sort of a newbie in the sense that I never really approached the aquarium process in a professional manner. In fact I only ever had a 29g freshwater community tank that did great but I never really changed the water or even knew about the nitrogen cycle. I had duo filters on it though which probably helped me out in the long run. Anyway, I work at PetCo and before I get ripped a new one, I know, PetCo really isn't the best place to seek advice on anything. I asked the fish department head on the proper way to set up a tank since I have had the 10g since last month, he said to run the filter about a week and treat the water. I did such and tested the water and it was okay to add fish apparently. I don't know if it was because of ammonia in the water or too much fish introduced but out of the original 7 fish I bought for that tank(4 guppies, 2 platies, 1 pleco) only 2 still love to this day. Now I had the tank water tested and it was the worst ammonia the guy had ever seen. He said only to do a 50% water change one day and then wait one day and change it again the same amount, then weekly water changes. I've done that and just tested the water today and it's bad still. I have a couple of live plants in the tank as well. I also plan to set up a 55g and want to do it the right way, if someone could set me on the right path, I would appreciate it.
