Hello. I don't have water conditioner yet for my fish tank but may I add distilled water to the tank in the meantime?

Hi I don't recommend using distilled water in your tank as the "osmolarity" of the water can cause problems for your fish. Either pick up a bottle of water conditioner from a pet store or draw a large bucket of tap water and let it sit for 4 or 5 days. Some of the chemicals will evaporate out when left to sit, but it's not such an ideal option.
