big nutreant proublme

[hayden]

do i have to get rodi or is ro good enough? i read some where ro takes out 98% of contaminates and the other 2% are taken care of by the di. so do i need to get rodi or will ro take out enough stuff? i am on well water and it has a high minirel content and lots of nutreants causing an algae problem

RO will take out most everything but IMO it's worth it to add on the DI stage. With that you can manage true 0 ppm TDS.

I think if you are setting up a FO or FOWLR you could go with the just the RO, but if you are going reef I would definately go RO/DI

I use tap in my FOWLR.. never had the need to go RO or DI.
