I've got rays and would like to keep my nitrates as low as possible. My incoming tap water is 20 PPM nitrate. Should I start with an rodi system or is there a different train of thought on this? Thank you!
 
Check out chixlub(robs) juruense catfish. He's going to do the same thing. Run rodi and bypass a little tap so he doesn't have to remineralize it.

I'd contact an rodi specialist and let them spec a unit for you. Then you will probably have to cut that with tap water. I know the discus folks have a diy remineralize recipe that's cost effective.

These are my initial thoughts maybe someone with the same water issues will chime in
 
nitrates 20ppm from tap are you on well water? FDA limit on nitrates in public system is only 10ppm.. anyway I ran RO/DI for my discus because my tap avgs 5ppm nitrate per city water listings.... it goes 10-12 ppm during spring run offs. right now I run my 50 gpd ro/DI right to tank thru drip emitters and mix HMA filtered tap through another system of emitters to remineralize water .... all on an irrgation timer resulting in 100% wc per week ....there are quite a few good postings here and on internet on auto change systems and RO/DI units .. dont overthink it
