So you are saying that before one is to add tap water to a tank they have to grow out macro in it???
No.
but I guess you could say have a planted FW tank an use that water for the marine setup.
My main point is basically to balance out the tank with macro algaes and they use much less (or no) water changes to reduce the dependance of tank conditions on the replacement water.
So I am not saying you dump in delicate sps corals immediately into a tank made with tapwater. But to let the macro (or turf) algaes grow and condition the tank over a few weeks and add the bioload slowly. And to dose calcium/alk/mag to makeup for things depleted which also cannot be fully replaced with water changes.
And of course you have to provide the lighting and feeding and other needs of the corals as well.
But on the other extreme and most definately for fish and "easy" corals topping off with tap water from a commonly used cold faucet after it has been ran for a minute or so, will not result in the immediate loss of anything in the tank.
Bottom line to me is whether or not filtering/water conditioning is best done with chemicals, ro/di (or other man made) filters, or with thriving growing plant life.
but hey that's just me.
