I set up the 55g without reading much about a fry tank or a hospital tank. The more I read the more it's a good idea to get a small 10-20g to use as such. Here's my issue though...Am I going to keep this all set up and cycled, keep adding ammonia to use when necessary? If I don't use it for a year that's just a waste of time and money. My other thought is, I have bio balls in my filter in a bag, could I just set up when needed using the bio balls from the main filter for an instant cycle? I also have a second HOB filter that I haven't started using for the main tank (bought it for extra filtration but everything is fine).
