Ok I don’t have a system for ro. But I think the Walmart sells ro purified water for like 50 cent a gallon but have to take bottles with me. It’s a machine. I’ll check into it. It may be purified some other way.you can do your own testing if your supplier doesnt, go to any marine aquarium store or website and you can purchase a Lamottes or others test kit. But be warned they can get pricey. I used to do live reef aquariums and had to have these kits. To kiss it you can forgo that and use RO and supp your calmag as required.
