Question I am getting mixed signals from all over the web...wondering if you can help
me sort this out...I have a male betta in a 5 gal. aquarium and have had him
about 7 months now...I've been using reverse osmosis water in his tank all
along which he seems fine with...I always treat the water with aquarium salt
and water conditioner ...I've been hearing that I should switch him to tap
water and it makes me nervous but I want what is best for him...What is your
opinion on that?
Answer Liane -
The RO (reverse osmosis) water you are providing your betta is much better than tap water. The RO water has already been filtered, and therefore should not contain any excess chemicals or minerals. This means that your tank should not even require the water conditioner. However, adding water conditioner will not harm the inhabitants.
I use RO/DI (reverse osmosis, deionized) water for my aquariums. The water stays cleaner, and I don't need to spend the extra money on water conditioners as needed. My fish are doing just fine, freshwater AND saltwater.
Hope this helps to ease your mind and settle your nerves.
