RO/DI

[Jack]

Thanks a lot for the good, quick replys. Looks like I will have to do a bit more research than I've done. I will read that article in the Library section. It's gonna be a good investment, I just want to make the right one. I just hate how the 45$ DI cartridge needs replacement every 400 gallons. Ugh, what a pain. But now I'm curious and wonder If I would even need the DI... oh man, tough call. Does anyone just use RO and get away fine? Or is DI worth it? Thanks again
