I am planning my first water change. I am doing a 20 percent change. Is it ok to take out my skimmer, powerhead, and filter and clean them? Is it also ok to move rocks around to clean the sides of the tank? I have a few small pieces of coral. I do have a BTA on one of the rocks I want to move to clean behind. I saw a video on youtube that said to set up a 5 gallon bucket, put a pump in it and let it mix for 6 hours. Is this the best idea?
