I do absolutely nothing to treat my incoming water and tell my fish to adapt or move on if they don't like my PH. I use a food grade water hose and a metal sink to hose adapter along with Seachem Prime/Safe. I dump the prime/safe into the tank and turn the water on full blast. I proceed to sit back and relax. When I hear the water go over my weir into the overflow box, I get up and turn the sink off. From what I've read and my little bit of experience, treating water is a pain and usually not worth it. Fish can adapt to differences in PH for instance. As long as yours is stable, they are good to go.
