Hi. I have an RO/DI unit for my saltwater aquarium. My TDS meter reads 5ppm after the RO filter and 0ppm after it goes through the DI resin. For those of you that don't know what I'm talking about, RO means reverse osmosis and DI means Deionization. The deionization process removes all ions from the water.
Can I feed my plants (soil) DI water or should I go with RO instead?
