Oh I did not know you have nitrates in your tap! Here it's unheard-ofI do do water changes and I have an auto drip too as well as growing pothos. The resins are ion exchange resins.
My tap water comes out of the tap at 25ppm which is lower than many, I think the legal limit in the U.K. Is around 50ppm. I would like the resin to keep the nitrate from going above 30ppm between water changes (weekly)
Some people happily change water but do not even realise that their tap water is over 100ppm, I used to love in a place that had over 100ppm straight out of the tap; you can change as much as you like and it would not help unless you employed RO water and remade that up.

Yeah 50 ppm is the legal limit for Canada and Europe, 45 ppm here in the US. Over 100 ppm from the tap? Was that water from a well or from a treatment plant? Is your 25 ppm from a treatment plant?My tap water comes out of the tap at 25ppm which is lower than many, I think the legal limit in the U.K. Is around 50ppm.
