Abstract:
1. An aquarium water filtration system for sequentially filtrating and balancing a water pH level in an aquarium while cooperating with an existing water level overflow unit of the aquarium for maintaining a maximum water level within the aquarium, said aquarium water filtration system comprising: an incoming water line and a cartridge filter in fluid communication with said incoming water line for removing chlorine from water; a reverse osmosis (RO) filter in fluid communication with said cartridge filter; a potential of hydrogen (pH) level control mechanism in fluid communication with said cartridge and RO filters, said pH control mechanism maintaining a desired pH level, water hardness level, ammonia level, and nitrite level in said water, said pH level control mechanism comprising a pH mixing chamber having two inlet connections and one outlet connection such that said pH mixing chamber receives water from said cartridge filter and said RO filter respectively, said mixing chamber receiving water from said cartridge filter via a manually adjustable pH control valve, wherein said desired pH level of said water is accomplished and maintained by mixing low pH water flowing from said RO filter with high pH water flowing from said cartridge filter in a proportionally controlled manner using said manually adjustable pH control valve, wherein said outlet connection of said pH mixing chamber provides water to said aquarium at said desired pH level; a plurality of valves in fluid communication with said cartridge filter and said RO filter for controlling a flow of said water into said aquarium while preventing back flow of said water out from said aquarium; and a waste water drain line in fluid communication with RO filter for directing waste water byproduct away from said aquarium filtration system.
