that was the first thing i looked for as I saw Bily's post about them. I still don't have a QT set-up. I don't seem to have the room so I do invite my own deamons l will admit that. I scraped the closed loop for awhile and just put a more powerful pump in the return. I'm still going to ues the extra 4 inlets with some valves to help flow direction. I should get about 3000gph turn-over and enough velocity for them. the fish we're havin a hard time swimming when I went balls out.as for pic...i sure do have some with actinics only tho....
for some reason my camera will not pick up flourscent greens. or flourescents of any color really. Or they just do not photograph well for me....
