I read about all sorts of methods to correct water chemistry problems. However, no method seems to be more effective than a simple routine water change. Tell me I'm wrong. I don't know if other people who may be OCD like I am but when I get bored at home; I get ancy about my water quality. When that happens, I do a partial water change. One time, I changed 20% of the water twice in one week. I don't know why but it just felt like the right thing to do at the time. Does anyone ever have that urge?
