Topping off with bottled water?

[rittz]

Is it safe to add regular bottled water to my aquarium without adding any chlorine remover or anything?

Generally not a good idea for two reasons. One is that bottled water often does contain chlorine just like tap water. Another is that it is often void of minerals needed to maintain a healthy pH. Some people use bottles spring waster, but I avoid the whole issue by just treating my own tap water. That assumes that your tap water doesn't have really high nitrates or a very high or low pH.

Thanks, didn't think so. My friends Betta lives in nothing but bottled water. Its obviously too risky for me. Thanks for helping!

My pleasure. People do all kinds of things with bettas that they really shouldn't. They are remarkably hardy fish, but they would be better off with pretty much the same treatment as other freshwater tropicals. Have a great night!

Same to you!

Use RODI water only if your tap water is poor quality.
