Ok, so I upgraded my tank to a 37 gallon and I wanted to do this whole thing as best I could. The transfer was successful so far. I purchased a RO Buddie 4 stage and was just about finished filling the tank when I noticed the sediment filter was a very dark brown. I checked the the water and it was reading 30ppm. The water pressure was still at 50 psi. I contacted Aquatic life and I was told that because I am from New York that I really needed a pre sediment filter to lengthen the life of my unit. I only produced 25 gallons, so you can imagine my surprise. My ppm before using the unit is only 54 ppm. I have a few questions. Does anyone else have this problem? I live in Bensonhurst Brooklyn. Will the pre sediment help my situation? There supposed to last 6 months. At this rate, I will be buying them bi weekly. Another thing, they sent me links for the pre sediment canister and filters. What micron size do I use? Sorry for the lengthy post, but I’m still learning.
