I watched a YouTube video today that said water conditioner for fish can make tap water safe for plants, too. Have you tried this? Would you agree? I spend about $40/month on distilled water, so Iām open to an easier and more cost-effective option, if it really is just as good for my plants. That being said, Iād probably still water my most finicky plant friends (spider plants, rattlesnakes, & stromanthe triostar) with distilled.
