My Christmas present to my self came in today! I paid like 18$ for the TDS tester on ebay, just the basic one. In the mail came the dual inline TDS tester with the line adapters and stuff, I think this one was a lot more than the one i bought. So thats a good deal I guess. I tested my tap water and its reading around 270-300 ppm. I tested my RO water and its only reading 003. Does that seem reasonable for just a Coralife RO unit? No De Ionizer. Or is this tester off? Anyone else have that dual inline TDS meter? What do you get for results with yours?
