If boiling must be small amout. Is the a store near you with RO water dispenser. I buy 5 gallons RO water at $1.60 just a thought.Can I use tap water to make my saltwater for my aquarium if I boil it first? If so, how long should I let it sit before I do my next water change??
But if have to use tap water, use a water conditioner. Aerate(salt mix) for 2 days, then use
