I dont know how many people use the life guards now but not to many on here im pretty sure. Just look at the whats in you stand thread for one none or hardly any when i searched that. I used them on my old 240. And tried to get info from these guys on them and sand filters, and bead filters, no one used um so i got none. My next big tank. Im deffenitly using one of those ocean clear bead filters. With a set of life quard in line, mechanical, bio, and heater module with a uv. Cheap as hell for what you get for performance all is inline. Every one on here for the most part from what i c and i read tons of threads on here use either canisters, or wet drys, or some kind of diy sump. All you ever here on here is fx5 fx5 fx5. They are great cannisters but not enough people utilize set ups like you just set up.
