It is recommended that I let tap water stand for several days before using it on my lady slipper orchids. Instead of having buckets of water sitting around or buying distilled water, could I just use tropical fish water conditioner drops? If the drops instantly make tap water safe for baby guppies, wouldn't they make it safe for lady slipper orchids?
An Instant Water Conditioner for Lady Slipper Orchids

Water conditioner drops for fish tanks will not rectify hard water and it is hard water that is a primary concern for lady slipper orchids. Hard water is water that has high mineral content. The reason you were instructed to let tap water stand for several days is so that the hard water deposits could settle to the bottom. Water conditioner drops for fish tanks serve to neutralize the chemicals (chlorine) in tap water that may be harmful to fish.
