Hi, quick ? My rodi water has high nitrates(40-same as the tap) I am going to replace the prefilters and it is close to time to replace the di so I'll do that too. Will this work for the nitrates or do I need to replace the membrane too? I just ask because if so I need to order the membrane but I have the others on hand.
Thanks
Thanks
