Not really on purpose. I have water mixed up I just have been too lazy to do it. My recent triton test was spot on and nutrients are where I like them, so why bother?
My tank has never looked better in its whole life as well. Don't know if it's related or pure coincidence....
I have a new tank sitting at the lfs waiting for me to move, so it'll be getting a large water change here soon enough and everything will likely be ****ed and turn into dog turds soon enough.
