I have a qt set up now and there is only 2 more fish in it that has to be moved to my DT which will be done by the end of the week. Everything in that qt went pretty well for the most part.
After the last 2 fish are moved can I just change half of the water and reuse it for the new fish i buy or should I be changing all the water?
