[quote=reefjitsu]A sythetic SW mix made with RO/DI is going to be better for aquarium use than natural SW. In an aquarium, certain elements are rapidly depleted, a good synthetic mix will help make up for this.QUOTE]
I agree!
I very recently set up my first SW (from a FW background). One of the first things I bought was my own 6 stage RO/DI. I have full intentions of making my own SW from day one. Simply for the fact of not having to drive to go get it and the and the savings over the long haul. Plus what if my LFS
closes up or I have to move? I may not have "the best" system out there but for the small investment the water is just fine. I must admitt though, filling my 120 tank and sump the first time with it was a hassle. Just spending the money to buy it and pour it in during set up would have made things much easier.
