Aquarium Advice FINatic
I've hooked up my new RO/DI in our new house. Water supply is well water with a pretty decent pressure (haven't measured yet). Before RO I get a TDS of around 425-450ppm. After RO I get around 100pppm TDS and after DI..I get 0ppm TDS. My concern is I wanted the RO portion (which we drink from) to knock the nitrates out of the tapwater. We live in a high farming area and our well water has nitrates that are off the scale of my Seachem nitrate test kit. After the RO filter the nitrates test around 10ppm or so. Does anyone have any real world figures along these same lines? Just curious if these results are too be expected. TIA
