Clean or Buy new RO membrane

[McShnutz]

That would be the last stage in purification after the Ro membranes. It takes the mineral content from about 20 ish ppm to 0ppm. It’s primarily used in hydroponics, aquaponics and aquariums. It’s not totally necessary for horticultural applications but it has made a difference in my recycling of LOS. Pure as the mountain snow. Nothing accumulates and I have complete control over values in my substrates.
