Don't forget that you will need to change the filters on the RO/DI system. I change mine every 6 months.

Good point. Filter, resin and membrane life will greatly depend on use and source water. I have had my filterguys ocean wave + for well over a year and have not changed out anything yet. PO4 and NO3 are still zero in the end product and I have a TDS reading of 003. I filter 60-80gals/month and will get concerned when I see a TDS reading of higher then 008.

If you want to be real thorough, get a hand held TDS meter. Even my cheap hand held is more accurate than the dual inline one I have. The popular dual inline tds I have is off about 10 tds and I cannot calibrate it

RO/DI is the way to go. If you have a good foundation (your water) then you will have fewer problems or at least can eliminate one source. Doing regular PWCs is a good idea. I have stuck to doing PWCs every other week and it has served me/my tank well over the last 3 years. Keep in mind that your RO/DI water is going to be cold so heating your water when you mix your SW up is needed! Also make sure that you let your SW mix for at least 24 hours before you do your PWC.
