Thanks for the web site, Allivymar! (teeny print though!) I remember staining cells in microbiology lab in college to see if they were gram positive or negative, but that's about all I remember!
I think I'm going to do something a little different with my tank than I originally planned. I did change a gallon of water, and add the last dose of Kanacyn tonight. I was going to leave on Friday night with the carbon filter running to remove the med. Now I think I will change 2 gallons of water on Friday morning and put the carbon filter in. About 6 hours later, roughly 3 pm, I'll take it out and check the ammonia level (hopefully it will be 0 or close to it). I'll put a teaspoon of Bio-Spira in, then we'll leave. I was thinking about it, and I just can't leave knowing the ammonia has been high, so I'll speed up getting the med out, instead of letting the carbon filter run all weekend while I'm not here. Then I can put the Bio-Spira in, and hopefully have a little peace of mind that the ammonia will not be high again while I'm gone. Does this sound ok? I hope the carbon can remove enough med in about 6 hours so the Bio-Spira is not killed off.
