I do not want to get an RO system due to the large amount of waste water. I am wondering what would be the best option for filtering my tap water for water changes. I am going to be doing 2-3 water changes a week of about 50-75 gal. each in my discus tank. looking at some 2 cartridge systems like you find at HD and Lowes. What would be the best inline filter system? let me add I want to stay under or around $100 if possible
Thanks
