I hear ya I really didnt want to run carbon but the odor of my tank forced me into it
Did you go the phosban reactor route?
I made my own reactor it hold 2 1/2 to 3 cups and run it off a rio600 pump it just lays in the sump killed the smell in 4 days and a noticeably clearer water. Only cost about 3 dollars to make it. I just was concerned about lld in my tangs but I think Ill just run it as needed may be 2 or 3weeks at a time then same time with out.
