I read a bit about it and see it is somewhat popular for reef aquariums. Do any of you use it for freshwater and are the pros over tap water really worth it? I can buy a system for $100 or buy water from a guy for a quarter a gallon. Since I will be doing 15% to 20% pwc's weekly I was considering it. Let me know.
