What is the best way to do a PWC on a tank with fish in it? I have only changed 5% of the water once and that was during my cycle, which is easy. I plan on doing about a 10% water change this weekend and would like to know how you guys recommend going about it. Is it better to get one of those pumps that drain the water out, or just taking water out via a 1 gallon bottle (or something similar) safe and stress free? I have 4 cichlids and they are very nosy about what is going on, so I don't want to stress them out too much.
