I am confused and not certain if this is the forum for this. Do I need an RO/DI unit if i only have FOWLR??? Should i Just get the RO or DI instead?
 
Moved to hardware/equipment forum.

You need a ro/di unit if you have any trace of no3/po4 in your tap water. If not it's not needed but still helpful in providing the purest water possible for your tank. RO only water can still have no3/po4 but ro/di filters out all harmful elements in tap. DI alone isn't recommended either since the resins are used up quicker.

EBAY has a ton to choose from at reasonable prices.
 
Thanks a lot that clears up everything. I live in an area where the water has lots of calcium, not certain of the other stuff , will buy test kits to check it out.
