Hello all I'm a new member here with a new pond (my first one in years) I have taken over a year to build this and I love it. I am about ready for the water and filtration. Alittle background on myself I own a water filtration company specializing high end equipment for restaurants so I have lots of used and new equipment tanks, carbon, different medias, filters. \nThis was my thought for the filtration I have a small carbon tank on the inlet of the system ( the float)\n9"x 44" tank with 1 cubic ft coconut carbon down flow\n9"x 44" tank with 1 cubic ft sand down flow\n9"x44" tank with bio balls up flow not sure how many to put in or if that tank size will work\nUv light.[ATTACH=full]66149[/ATTACH][ATTACH=full]66150[/ATTACH][ATTACH=full]66151[/ATTACH]\nAlso not sure of what order the filtration sould be in\nDo I need anyother filtration or does something seem wrong with what im thinking. Im not sure yet on what the actual gallon size of the pond is I will have a meter on when I fill it.
