i use UV in my tanks... once i forgot to plug in the UV after WC and went overseas, i came back to a tank filled with brown algae..... did some scrubbing, on my UV and i never see them again...
Filter socks for mechanical. Wet/dry for bio just in case and a heated filtered drip. Also agree that if money was no object this would be for a fishbuilding housing thousands of gallons, I guess the 210 could hang out too.
