Hey, Lindsay...I feel your pain...check out some of my posts on here and you'll probably ignore everything I'm about to say, but trust me...Alli gives great advice and she's kept our fish alive when they otherwise would have gone to the great fish tank in the sky. Until I found this site, I had an execution tank (well, after Sunday that didn't change much
).
Anyway, what Alli says works. Daily 25% water changes. I did it for six weeks before I got 0 ammonia and 0 nitrites. Basically, when I bought my test kit (the same one you have, by the way, purchased also at Petsmart) and came home and tested my water, (the same day I had Petsmart test it and they told me all levels were fine), the home test kit told me my ammonia was 3.0...don't know how that can be "fine", but anyway....
I began the daily water changes (me and the guys had lovely conversations every morning) and after about three weeks, the ammonia dropped to 0 and the nitrites started rising. They went up to about 2.0 (overnight every night, by the way) and then dropped to 0 officially on New Year's Day.
I scooched around the gravel every day in different areas, just to get the gunk out, but not the whole thing, so the bacteria was not affected. I also ignored the filter manufacturers directions (at the suggestion of MANY on this board) and let it get gunky and gross. I did change the entire filter (medium and charcoal) after we had a sudden temp drop in the tank and we lost 7 out of 10 fish. I now wish I hadn't done that.
The white wavy stuff appeared on our glass, too. It went away by itself. Now I'm dealing with an algae bloom. Does your tank cloud look green if you look at the tank from one end? Ours looks white facing the front, but green if you look through the ends (check out my gallery and you'll see what I'm talking about). If yours looks like ours, the brilliant people on this board have diagnosed "algae bloom". If you go to Petsmart and ask, they'll offer you chemicals for everything wrong with your tank...saw that today when we were buying plants for our 10 gallon. A guy came in and asked about a nitrate spike...salesman sold him something. I asked about the algae bloom. He handed me some sort of algae chemical remover (anyone ever used the stuff with success?)
Anyway, please, please, please listen to Alli...she'll get your tank straight for you in no time...now, if she just could have psychically known about my heat problem last weekend and telepathically reset our furnace....
