I'm doing a 50 percent water change on one of my 55 gallon tanks, but I just realized the faucet adapter for my water hose is broken. Do you guys think my fish will be okay in half their usual water with the filters off and the bubbler going while I go to replace it? I don't have enough de-chlor either (I hate it when my sister uses up almost all the supplies without informing me so that I can avoid this sort of situation). Or should I just risk the bucket method with my flimsy three gallon buckets?
