nah i'm not gonna fix it...don't get me wrong the emperor did its job great but the sleek look and non cartridge replacing ac just seems the way to go soooo i got a free emperor 280 if n e one wants to tinker w/ it and fix it and lives in the dfw area of texas is more than welcome to it....i'm a person who also likes to overfilter his tanks i just don't think a ac 200 is enough...now can i just use 2x ac 200 so that way i only have to get another 200 or just use a ac 300?
