okay i have always heard soooo much about ro/di water....and myself i have always drove across town to fill up a few five gallon jugs to do water changes...but lately my gfriend and i have been looking all over for a ro/di unit and everywhere that i go other than fish stores only handles ro units...what is the real differenence? at one lfs they even went as far as to say that ro water is actually better than ro/di water for saltwater tanks because there are some positive elements which are left behind...so is the only major downfall to reverse osmosis without dionization that you waste far more water? is ro water going to cause algae problems?
