I'm trying to remember but you have very high nitrates in your tap water right? You're lugging it from your friends place? That would be a pain. I put a RO
system under our kitchen sink for $150. The problem with that system is the storage tank. You need a very large tank to hold the water that's filtered. These filters don't filter "on demand". They have slow filter rate so the filtered water needs to be stored. I know it's mainly used in saltwater tanks but not so sure about freshwater applications.
