Hi i am having problems with my R/O unit the water is coming out with high nitrates in it. I just replaced the 3 cartridges a week ago and the membrane about 5 months ago. The only thing i could think of is my local LFS told me i could use a 75 gpd membrane instead of the 50 gpd its made for and it is shot already? Any thoughts? So i have to a water change because my nitrates are super high so can i use tap water on a FOWLER tank without issues? Been using an R/O for years and an LFS owner said it is not necessary. Thanks Tom
