Hi, I've been posting frequently because this seems like a great source of info for fish newbies such as myself, and I had a total newbie question about water changing. Whenever I have "changed water" in the past, it has included me taking out some water with my tank pump, and me adding some ~room temp. water along with water conditioner. It feels like there has to be something more to it, and if there is please tell me. What I plan to do from now on though, is take ~15% of the water out, put some new water in a pot I have (reserved for fish stuff), and add conditioner. Once the conditioner is finished with it's work, I'll just dump the water in. Good strategy or no? Also, should the water be at perfect temp., or is it ok to be slightly colder?
