I have been keeping sw fish & reef tanks for a long time, but have never used ro/di filters allways just plain well water with few problems. Anybody pros. cons?

I'm having phosphate and CO2 trouble with my well water.Presently,all that is being used,is a 10 inch sedement filter,and a 10 inch carbon filter.I'm going to buy an RO/DI sytem to put after these pre filters.Before,the DI,I'm going to bubble the CO2 out before the DI units.John
