Cruella,
The only thing I can recommend about every problem you've encountered so far and almost every problem you will encounter, is to read up on this hobby and do your research. From the sounds of everthing so far, you are 110% gung-ho, head first, no looking back (or forward for that matter) into the end result. Keeping up this pace, I can almost guarantee you will end up losing your entire tank, and be so discouraged that you leave the hobby all together. If you truely are interested in the hobby and keeping a heathly tank, take all of our advice (and a lot has been given) and SLOW DOWN. I'm sure there are a lot of experts here that will agree with me that you're heading down the wrong path. So please just read, listen, relax, and take things slow.
