I'm probably gonna get one anyway. I was looking at that $65 one on eBay. But on a slightly different subject how long would RO/DI be good for? For example, if I made 50gal and used 25gal to mix with salt how long would the fresh and salt last. I assume I would have to keep both covered and circulating right? Would I have to exaust my supply before adding to it or could I continually top off my supplies as they get low? Maybe I should have just started a new thread. Thanks
