My TDS PPM is 032 before Di and 003 after Di, Do I really need RO/DI unit or is my DI unit enough?? Does DI remove clorine or is it the RO or A. Carbon that does?

Thanks

I have to chime in and say that purchasing an RO/DI unit for my reef tanks was the best single investment I've ever made......it's well worth it and you can be assured of water quality - -

Vince hit on it. The RO will fiter out a lot of bad stuff that if left in, will SERIOUSLY reduce the lift-span of your DI cartridge.
