I live in Florida where the water is high in ph and very hard. I currently have two tanks, one is a 110 gal and the other is a 75 gal. I have Angels in the 110 gal tank and African's in the 75 gal. All fish seem to be doing fine-though no breeding is going on which is fine with me. I am setting up two other tanks, a 375 gal for Africans and a 350 gal for an Angel-community tank. Would you go to a RO system if you were me and why?
