Steve,

Thanks for taking the time to do some research for me. As mentioned to
Mary, I'm doing my best to keep the levels as low as possible without
drastic 100% water changes.

Despite the early losses, I do plan to keep up the hobby - it's very
relaxing to sit and watch the fishies. :-) I plan to do some
experimenting with the hospital tank in an effort to master the
"fishless cycle" so that if / when I upgrade to a larger tank I can do
it right (and so that the hospital tank is ready to go, if needed).

Thanks,

Liz
