So I did a water change today--very simple. I had my husband help me but could have easily done it without him..took us 20 min. tops after we got the replacement water to temp. We also decided today that we'll keep Rosie as long as she's not aggressive toward any other fish we add. So I definitely plan on keeping up with water changes to help her through the cycle. Thought you all should know! and thanks again!
Glad to hear it wasn't too frustrating! Once you get the hang of it, it will take no time at all! I can do all four of my tanks (I can only use my "Python" on 2 tanks, the rest are bucket brigade) in around 45 minutes.
