Any Coastal Reefers using natural sea water?
Well as I research and plan my first reef, I seem to come up with more and more questions. Here's the latest. Does anyone use natural seawater in their reef? I was curious if I could collect some (very easily where I am), heat and age it for a couple of days and use it for water changes. I was thinking that this might reduce the need for dosing the tank. Anyone tried this or have any thoughts on it?

I think there are a fair number of us who use artificial sea water and who don't dose anything... let us know what you are planning to dose and perhaps someone with more experience can tell you whether they think it is necessary or not.

Ken, I've found that due to fw runoff, much of our costal waters around the Island have reduced values of SG, pH and Ca. And even if the levels were fine, you'd still consume them at the same rate as artificial sea water. Dosing, if you need to, will be the same.
The other side is pollution, dying plankton and possibly other contaminants. For the cost of an average water change, I prefer to stick to IO salt prepped in RO water. This way I know where I stand(recent bad salt aside).

FYI...The Vancouver Aquarium uses NSW from about 200m offshore from Stanley Park. It's pumped into the bowels of the aquarium and goes through an entire filtration system. They find it works well for their use with the exception of their reef display...synthetic only.
