Every one I've ever talked to make it sound like an utmost utterly evil thing to use tap water for saltwater tanks. I tried asking on this forum but I was told that it would be doomed to fail, so I use ro
water. What I don't understand is that they make water conditioners for saltwater that supposedly get rid of chlorine and chloramine and detoxify metals. However I was told that is still not a remedy to the metals problem and that down the road it will kill everything! So if someone doesn't have ro
water, don't even bother. I installed an ro
unit for $150, because i felt like I had no choice. But it makes me happy to hear that tap water works for someone.
