i broke down my saltwater tamk a few monthes ago a decided to set it back up freshwater

i never ran such a large freshwater take before so i think i am going to try to operate it with a saltwater mentality

its a 140 gal tank (4ft long 2 ft wide 28" tall) with one overflow

filtration will be a 30 gal sump with a planted refuguim

lighting will be 4 4ft vho's

circulation 1 pump running the sump about 500 gal/hr and 1 pump running a closed loop about 650 gal/hr wich i'll probably crank down to about 300 gal/hr

and lastly if i use r/o d/i (0-2 ppm tds) water would i need to add trace elements
does this sound good for a community tank

thanks
