Just glad I didn't wait another half an hour to go downstairs!!!So your options are the water goes stale vs the water goes stale and your canister filter motor overheats? What are you gaining by leaving them on?
If the impeller is moving , there is movement so the water should not be stagnant and thus should not go stale?
No?
Haha true.. just always thought little movement better than no movement....Moving where? The water is madly spinning in a little one inch circle within the impeller chamber. It's not moving out of the filter to be reoxygenated.
Protip: Even if you're sitting next to your tank while doing it, don't play video games while waiting for it to drain.
Protip 2: REAALLY DO NOT play video games while waiting for it to fill.
I do it all the time. Playing the borderlands prequel.*Sigh* Don't listen to me. I'm filling my tank right now while playing video games.
