ugh... now i feel sick...
what kinda HOB filter do you have? Wet/dry?
I just have a fuge, but i don't have that much LR, so i wanted to get a HOB wet/dry, and have the return water from that routed down to my fuge, and then route the fuge to return to the tank... I don't have enough room in my fuge for a wet/dry section, as my fuge is only 10 g, and is housing my protein skimmer... *sigh*
