The essential elements in ocean water most likely are not coming out of your tap water. Regardless of what type of water you use, are you not adding any chems, trace elements,, kalkwasser, etc. to your reef? I never look to water as my sole source of nutrition for my corals. I would prefer to have a blank slate to start with.Crevalle said:There are some minerals included in aquarium salt (coralife, instant ocean, etc), but it still isn't equivalent to sea water. In other words, it does not replace the essential elements in the ocean's water. It matters in a reef tank because the more you top-off, the more you are stripping the water, rather than replacing minerals, despite at a slow rate.
yes mam and yes again. Different locations have different minerals, bacteria, parasites present in all bodies of similar water all over the globe.Doesn't the mineral content of spring water vary greatly, depending on the source? Couldn't you have too much of some minerals by using spring water?
