I use RO/DI to cut with tap. My tap is super hard so I have to cut it 2 parts tap : 3 parts RO/DI to get my water at 4kh 8GH. My DI is getting killed, I just replaced it a month ago and it is already turning colors (showing the need to replace it) Do you guys think I can get away with just using RO? Will RO only water have any measurable GH or KH? Thanks
