RO in plantation

[Chrisq0904]

For those who make RO in plantation what is your TDS on the water in? I have the BRS RODI system and when I first start making water my TDS is around 15 then drops to 0 within 5min or so, my TDS out is always 0. I'm not too worried about anything since TDS out is 0 but does anyone else in plantation get similar results? Also, I flush the system for a few minutes before and after making water.

My results are about the same. I changed over my 4 stage to include charcoal for the chlorimines they have in the water here. When the tds get to 1 on the outlet I change all filters.
